When does a heavy drinker become an alcoholic? My sister is 27 and has a great job and should be having the time of her life - she lives in Dublin. But I think she has a real drink problem, I've known her to hide drink in her bag when she (very infrequently) stays with me, I know she drinks most nights after work and she gets totally wiped at the weekends. She has had so many scrapes and what should be wake-up calls but she just seems totally set on a life of self-destruction. I'm going up to Mums tomorrow for a couple of days and she is there - well should be - she went out last night and hasn't came back yet. I am torn between rage - my parents are in their 70's and I want to keep their lives free from any more hurt (we lost a sibling in a road accident a few years ago)and trying to help her deal with whatever pain she is in. Has anyone had to deal with something similar - I feel out of my depth and very worried.
