I can relate to trying to control it. I used to go to a bar and sip my beers so they would take longer to drink. My problem was it that once I became buzzed and started to have a better time, those sips would turn in to gulps. Before I knew it, beers were going down in a few minutes. Once shots would get involved, lights out.
I decided to start practicing at home, just drink a 6 pack. Every night. After weeks of "practicing" I would return to the bars, but as long as they were still serving and I had money; I would always over-drink what i said i was. After too many blackouts, i didn't want to go out anymore, so i did it exclusively at home which brought on more problems.
My plan this time, is to simply come to terms that I suck at drinking and give up trying to make it work for me. I've tried countless times in the past and the same thing happened each time to mess it up...One Sip. Stay away from 1 sip. Think of Pringles (once you pop you can't stop)
