so last night i went to a bbq and had probably 4 or 5 beers over the course of 4 hours. didnt get drunk. got home. passed out. middle of the night i woke up to throw up and felt like i was going to die. my head was pounding. cold sweats. had to call out of work today. now on a typical weekend i can down scotches and have absolutely no problem the next day. i feel great. im in good shape id say. my diet is on point and i work out a lot. dont smoke. why is it that beer does this? does this happen to anyone else?
