Throwing Up After Drinking

Chat, please help me out. Since I started drinking, if I drink a certain amount of alcohol on a night out, I will wake up the next day and beginning throwing up about every 30 or so minutes for literally 6-8 hours. Why do I do this? I know I’m not the only one who has this reaction, but in my sphere of influence, I have not met anybody with this problem. Why can some drink a lot, get a hangover, maybe throw up a couple of times, while I react like this. If anybody knows the science behind please feel free to share. This issue prevents me from ever drinking heavy, but sometimes, if the night permits, I’ll drink more just to wake up with this inconvenient problem.
