You roll over, stretching your hand out searching for your boyfriend's heat. You peek out of one eye, when you feel only cold on his side of the bed. 

"Bucky?" You ask softly, still half asleep. You open your other eye, looking around the room curiously. You blink in surprise, when you the clock, which reads 2:43 in the morning. "James?" you call a bit louder, not wanting to wake him if he had fallen asleep on the floor or couch again. 

Ever since you two had started dating, and even before that as friends, he had a hard time sleeping comfortably in the bed. Given everything that had happened to him, you didn't blame him, but you did miss him on the nights when he couldn't sleep with you. 

You got up, walking out of the bedroom, looking for signs of where he had ended up. You listened carefully, grabbing a bat you both kept in the hallway in case of a break in. "Buck?" You called, mentally cursing yourself for forgetting your cell phone on the charger, as you'd normally call Cap, in case Bucky was with him. 

You stiffen, as you hear a loud boom coming from the bathroom, at the end of the hall. 

"I have a bat, and will beat the crap out of you!" You yell loudly, as the only warning you'd offer. 

"Y/N?" a weak, male voice asked from behind the closed bathroom door. "Don't attack, it's just me." Bucky added, not wanting to be beat up by you, especially when you were in a protective mood. 

You put the bat down against the wall, visibly relaxing you hear his voice. "You okay?" You ask, wondering why there had been a boom. 

"No," came a strangled reply, followed by what sounded like a hiccup. 

"Can i come in?" You ask, walking up to the door, silently testing the door handle to find it unlocked. 

"Y... yes...s..." He stammered in between more hiccups, that sounded worse and worse. 

You open the door gingerly, gasping as you see Bucky curled in a tight ball on the ground near the tub and toilet. "Love?" you ask softly, noticing a thin sheen of sweat covering him, having soaked completely through his loose t-shirt. 

"I think my body hates me." Bucky admitted weakly, looking up at you before hissing and hiding his face against his metal arm. Now the boom made sense, since he was a bit clumsy at times with his metal arm. 

You kneel in front of him, running your fingers through his sweaty hair, immediately noticing the jump in heat coming from him. "Is it the serum?" you ask, knowing that there were times the serum fought him, and made him miserable. 

Bucky shook his head, barely, which caused mild groaning to emit from his lips. "No, this is something worse." he ground out, a soft whimper quickly covered for by another round of hiccups. 

You nod, inwardly relieved it wasn't the serum acting up again. You made a mental note to ask Cap about that, as you sat down and patted your lap. 

Bucky inched upward to rest his head on your lap, curling up tightly as the hiccups wracked his form. "Damn, hiccups hurt." he grumbled, as a soft burp emitted from his lips, causing him to pale and gulp loudly. 

"What's going on?" You ask, resuming putting your fingers gingerly through his hair. 

Bucky stiffened, not speaking or moving, as his back bucked in his body's effort to hiccup and burp. 

You look down at him in concern, moving your hand to his back, before getting an idea of what was happening, to your poor boyfriend. 

"Gonna puke?" you ask him, watching his face closely. He remained rigid against your leg, not moving, even as he held his breath. "James? Are you going to puke?" you ask him firmly. 

Bucky looked at you, offering a barely perceptible nod, before a gag rocked his floor. He used his metal arm to push himself upright, and to the toilet, faster than you'd ever seen him move before. 

He gagged again, groaning as only saliva came out of his mouth and landed in the water. 

"It's okay, just try to breathe." You say gently, moving to sit on the tub's edge, so you can help support him if needed. 

Bucky looked at you sideways, briefly, before gagging hard and bringing up a small amount of water into the water with a soft splash. 

"Oh honey, its okay," You say gently, before an idea hits you. As someone from a different era, he may not be able to handle the taste... "Have you ever tried pepto?" you ask, getting up and showing him the bottle. 

Bucky took one look at the bottle in your hands, before vomiting heavily in the toilet, with a loud splash. He sputtered in surprise, gagging up more and more undigested food and liquids. He finally stopped, before dry heaving set in, only to lead to more vomiting. 

You rubbed his back lightly, flinching as his back bucked each time moments before more joined what was already in the toilet. You move briefly to flush away the vomit, as the second round of dry heaves set in. 

Bucky sank against the tub, panting hard as he tried to recover from what had just happened. His cheeks were flushed, he was drenched in sweat, and he was shaking and shivering nonstop. 

"You good?" You ask him, watching him thoughtfully, debating what to do to help him. 

Bucky shook his head no, before gagging up a small amount of bile down his shirt. "Sorry." he slurred, looking and sounding beyond exhausted. 

"Its okay, let's get that shirt off you, and give you a rinse down. Arm on or off?" You ask nonchalantly, so he wouldn't feel weird about it. 

Bucky frowned for a moment, before hiccuping more bile up and onto his shirt. "What the hell?!" he grumbled weakly, glaring at his shirt as if it had personally betrayed him. 

 You chuckle softly, earning the glare towards you, before helping him gingerly remove his metal arm, followed  by  his t-shirt. Next you reach for his pants, making sure you don't make eye contact, as you help him strip and get in the tub. 

You turn the water onto lukewarm, then wait as the water fills up the tub, watching him closely in case he was too dizzy to stay upright on his own. 

Bucky was leaning heavily against the shower wall, his eyes closed tightly, as his hand pressed to his stomach. "Think I am gonna puke." he mumbled, as a green tint colored his cheeks. 

"That's okay. The water will wash it away." You say kindly, as you reach up and guide him down to sit on the edge of the tub. "Is it just vomiting or is anything else bugging you?" you ask, hoping it was only puking, not puking and diarrhea too. 

Bucky sat down with a low thump, before starting to dry heave. After a few minutes of dry heaving, he vomited on the tub floor, flinching at the loud splattering noise. "Just vomit." He whispered, once he got a chance to catch his breath. After speaking, he was right back at it, dry heaving and vomiting again. 

You reached up, removing the extend-able shower head, and hosed down the mess, making it vanish much  to Bucky's visible relief. Once he stopped trying to throw up all of his internal organs, he slowly stood up, and let you hose him down quickly, before he sat back down and hid his face with his hand. 

"What's wrong, love?" you ask, as you grab a fluffy towel and wrap it around him. You slowly dried him off, allowing him the dignity to handle with everything below the waist. 

"I'm tired. Can we sleep, please?" Bucky pleaded, after wrapping the towel around his waist to hide everything below the waist. His face was very pale, but he didn't look like he was going to be vomiting anymore, not now anyways. 

"Of course, let me get you some clothes, then we can go to bed." You say, leaving the room and returned a few minutes later to see a barely awake Bucky, who was shivering like it was the dead of winter. "Need help?" you ask gently, hoping not to startle him. 

Bucky jumped, his eyes hard and angry, as he stood up defensively, before swaying before dropping to his knees and dry heaving unproductively. "Take me, not her, not him. I will kill anyone you want." he said fiercely after dry heaving. 

"Oh Bucky, honey, its me. I am not going to hurt you." You say brokenly offering a hug, feeling tears pour down your cheeks, at the thought that he was flashing back. 

Bucky crumbled into your arms, sobbing harshly as the pained memories washed over him. "I..." he attempted to say, before hiccuping set in again. 

"Shhh... It's okay. Let's get to bed, yeah?" You say quickly, using one hand to quickly swipe your tears away to hide  them from him. 

Bucky nodded slowly, allowing you to help him to his feet and dress slowly. He numbly watched you grab the trash can, and lead him to the bedroom. He collapsed on the bed, curling up a bit, but not enough for there not to be room for you. "Cuddle please?" he pleaded weakly. 

You nod, before laying down, so he can lay against your chest. "Sleep, Bucky, its the best thing for you now." you say heavily, unsure how to help him anymore. 

"I know you were crying." Bucky mumbled weakly, snuggling closer as you pulled the blanket around you both. 

"Only because you were hurting." You admit, sniffling softly as you fought not to tear up again. 

"I'm not anymore, thanks to you, Y/N." Bucky slurred sleepily, as his eyes drifted closed. 

------------------------------------------------------------------------------------------------------------------------

You spent the rest of the morning sleeping with him on your chest, before waking up around noon to him vomiting in the trash bin.  Then spent the next 24 hours trying to help him get better; by the next morning, the vomiting was done and the fever was gone. 

I hope this was worth the wait. I apologize for taking a while to post, between this book and my 5 others, I don't have a ton of free time. But I will continue to update, even if its slowly.
