CleoAK,
wow...you sound so much like me. I also quit in my early 20's, no program. I did not drink for 10 years, then started again when my children were quite young. I drank heavily and daily for 7 years, until I was baker-acted for a suicide attempt. It has been 5 years since I've had a drink or drug and this time is different. I quit in an "AVRTish" way...I did not know of AVRT at the time.
I would encourage you to look into AVRT. And do not fear. The 7 years you did not drink are not "lost" and you are not a failure. While you did drink again, it is not productive to dwell. That is just another way for "it" to get to you, so stop doing that and move forward.
I'm thinking of you. I have complete faith that you can quit, if you so desire.
