Only you can decide whether you can moderate your drinking, Misscat, and even if I was able to drink just one shot, one time, I couldn't guarantee that I would be able to stop at 1 the next time.
Abstinence is safest. I know it's hard to not think in terms of never drink/party again, so why not try to stay in the present, and look for things to do that don't involve alcohol?
They say it's a test we can try in order to find out if we are true alcoholics - to try to stop at just one - but I don't like to play with fire, myself.
I hope that you keep posting, Misscat.
