I drank 3 cans of Red Bull hoping to get through my back-to-back exams since it's my final semester, but now I'm regretting it. I had one can in the evening, the next at around 11 PM, and the last one this morning at about 5:30 AM. After that third one, I started feeling really nauseous and ended up vomiting just an hour before my exam. I realized I mostly had them on an empty stomach. Even though I felt somewhat better after puking, it's been a while, and I'm still feeling weak and a bit off. I'm scared and definitely not touching Red Bull again. What should I do now, and what should I avoid to feel better?
