My "rock bottom" was DUI conviction. I was never a everyday drinker, just once every week or two, but I would drink too much and do stupid shit that I regretted.
I've cut down my drinking a lot since then, only had maybe 3 days this year of drinking since february. One year a couple years ago I didn't drink at all.
Having said that, I will probably be drinking tonight at a new years eve house party. And I am in Thailand in a few days so will might go nuts with the alcohol, I will try my best not to though, but it is hard with the nightlife culture there.
