Hey Jim! Reading your post reminds me of the opening of the old TV program, "Mission Impossible". Like "Your mission, Jim, should you choose to accept it, is.....!" Well it sounds like your mission is sobriety and we know that sobriety is not in any way "impossible". It's possible because we see lots of folks who have done it. And it sounds like you have accepted that "mission" and have taken that crucial first step. That first one. That's the big one and in some ways the trickiest one. And, as the Chinese say, "A journey of a thousand miles begins with a single step."
Congratulations on the beginning of that journey. You've got lots of companions here and elsewhere to journey with you. Stay close to them. It's possible to do it alone but it's better, and safer, to do it with others and also, if you can arrange it, with a friendly guide.
