To be honest my boyfriend should also watch his alcohol intake as he is a Type 1 diabetic. He drinks most nights after work, gets really drunk at the weekends but is rarely sick at the time. He gets hangovers which make him feel like sh*t but also doesn't realise that there's also a side of him that's not too pretty that comes out when he's drunk-it just takes a longer time to come out with him than it does with me (I don't have the capacity for drinking that he does). In my opinion he also has problematic drinking and from previous experience with other issues (diabetes related) I know he has a penchant for denial. I hope I can get him to understand. I did say no when he offered me alcohol last night so woop, woop!
