Hail and well met! I'm finishing up my first week of sobriety, and believe me, reading other people's stories and the wisdom and experience in the replies is a tremendous help. And posting and exploring ... wow.
Read, read, read. Many of us have gone from highly functional to functional to almost blew it to gotta get hold of this to crash and burn. It can take years, but why waste those years and why risk it? You sound like a determined "get it done" type of person. Whatever method you find that works for you, get it done. A bit preachy? Hope not. Don't mean to be.
