Binge drinker here too. Just weekends. The frequency of the drinking was not what made me alcoholic. It's what happened when I put alcohol in the system. Once I put it in all bets were off. I had no control how much I consumed. Your rationalizing sounds very familiar. Our minds tell us it is ok or that I will control it this time. That is the baffling and cunning part of alcohol. If you ask a moderate drinker about this they will not understand because they don't ever rationalize, they can take it or leave it. Weird I know! Bit once they have drink the allergy for more doesn't kick in. If you have that allergy the obsession to drink like a normal person has to lost. Because you can't change your body.
