Great posts here.
I think it all depends.
Some people like Mike and I seem to literally have been born that way -- to drink compulsively from day 1 when we drink.
Others work up to it.
But we all share the same thing at the end -- whether by nature or design we now drink compulsively whenever we drink (or a lot) and unless we want to live with the destruction that causes, do not drink.
I did not chose not to be able to drink normally, but I do chose not to drink because I am a compulsive drinker.
Why? I put that down to why am I short -- my sister is tall, why am I short? She also drinks normally. Lucky for her.
But I am what I am and I need to live as well as I can within what I was given.
Short and a compulsive drinker. Wishing I was tall is going to get me just as far as wishing I could drink normally.
Good luck.
