My boyfriend drinks everyday, whether it's a couple beers or liquor. He also throws up every single day, but most the time it's like mucus (he has really bad allergies). Not actually vomit. But on occasion he does actually throw up some days and it can be pretty horrific. He's also been light headed, he sweats in his sleep, and he often wakes up confused. He also has bowel movements at least 5 times a day. Anyone know what's wrong? Please help. He wont go to the doctor and I'm scared it could be something really bad.
