I recently read Clarissa Dickson Wrights book (spilling the beans) she is an alcoholic (hasnt had a drink for many years) and writes about her drying out period. Also she writes about hunting etc so its an enjoyable country read. It talks about addiction in some detail so would suggest you have a look. Secondly if aggression is a problem why not find an outlet? I was hitting the bottle a little bit too hard about 5 years ago, knew i had to do something, so i went back to play rugby after 2 years out of the game. It was a good move i lost 2 stone in weight, found sobriety had its strong points,
