Welcome patrisha!
This is my third (and final!) round of getting sober, too..... I had built up 3-4 years of sobriety both times (went to treatment, did 90 in 90, the steps, etc.). I'd be all gung-ho for the first couple years and then drift away and eventually think I could safely have a drink.
It's amazing how hard it was to stop once I got into the rut again, even with all the knowledge and tools I had from the past. Coming here two years ago helped turned me around and gave me something I could use anytime, night or day, every day. I haven't had a drink since. I think you'll find the support here really great, too ....... Congratulations on your decision - things really will get better!:ghug3
