It really is a horrific way to go. Two years ago I lost a childhood freind to alcoholism. Left behind a 2 year old daughter. He just couldn't put the bottle down.
Now that being said there wasn't a day that didn't go by where he didn't have several drinks. Its my understanding its not so much that you have 180 drinks in a month. Its that you had 6 drinks every day like clockwork with no chance for your liver to recover. You would be “better off” having 45 drinks on the four fridays and let your body repair its self the other 6 days.
