Alcohol is a lot like marijuana in that it creates huge cravings for food. I think people fail to realize the binging on food that often occurs after having a few drinks. I pretty much quit drinking a year ago. I used to be a daily drinker but now seldom drink.
I didn't notice any real weight loss when i quit drinking. Of course i really don't have much to lose. I was pretty much at my minimum weight when i quit. I did notice that i had more money to spend on other things when i quit drinking a 6 pack or more of beer every evening.
