What is it your coming off? I broke free of a nasty meth habit about 14 years ago and just ditched my booze this past December after 28 years of drinking and drugging. I have to tell you it is so nice not having anything control me. No voices in my head telling me what would take the pain away. Now when something floors me (this week was a doozy, death in the family and my nest being emptied) I can get through it on my own two feet.
When I used I always thought grief/sadness/anger would be to much to live through sober, but I actually find it so much easier to cope on my own.
Just don't pick up tonight. Throw out all the paraphernalia, poor out the booze, flush junk and pills, and take it a day at a time.
