A former partner of mine 'got it' when he tried a week without alcohol - he found it easy, that made him realise how much grip it had over me. If it were a choice I'd have stopped. I had many serious incidents, life threatening, and trouble with the police. I also got myself into a lot of dangerous situations (think getting into cars with men from bars I'd met in blackout, waking up not knowing where I was nor how I got there, no purse, no phone

).
Anyhow, it is difficult without support however you have to concentrate on yourself.
Sometimes non-drinkers make drinkers feel uncomfortable. Well if living a decent life is uncomfortable they can go jump(sorry don't mean that really, but I hope you do know what I mean).
I was out last night at a social gathering of a few friends, one has someone close who is suffering through alcoholism, this person said that they felt bad about having a drink on the table near me. It really wasn't a problem, I enjoyed my peppermint tea!
