Man, or woman, slow down I agree with Astro. I too drank vodka every night for well over 20 years but never stopped at 8 or 10, I don't want to talk war stories, but I mean to say that one cold turkey does not make a christmas dinner. (Bad metaphor I know).
Take it easy, step by step, go slowly and reflect. Posting here is such a positive move. There are other things such as rehab and meetings that can be so helpful because you see the others just like you who are struggling yet still achieving sobriety on a daily basis.
I hope that doesn't sound too patronising, I mean to be encouraging.
