Moderation only works if you are the type of person than doesn't care about drinking. This is a type of person that doesn't do things or go places that involve drinking. This type of person will drink one beer on a Friday night once every 3 months or have a few drinks once a year on New Years Eve.
For a person like me moderation never worked. I would rather have no beers than have one beer. During my 27 years of daily drinking I tried to moderate. On the rare few days I didn't drink I would drink twice as much the next day.
I figured I can only be a daily drinker that gets drunk everyday or a person that doesn't drink at all and for the last 47 days I have chosen the later.
