Hello,
This is for the original poster. You do realize that this is an illness, don't you? I hope so. You said you're happy and in a good relationship, but you still drink. I have formulated a theory on what this illness is, and without going into it, I'll say this. One thing I noticed about our illness is even when things seem fine, especially to everyone else, we still use. This baffled me for many a year. I finally realized a few things. One is that even when I think I'm happy because some things are going well, there is still an underlying feeling of discontentment in me. I'm just not happy with me, and how I feel. So I would use to try and make myself feel better about me. However, it was always largely unsuccessful. Even if I felt better while I was drunk, the next day I felt worse than before I drank. And the older we get, the longer the hangover lasts. I have concluded that in our brains there is a lack of the Feel Good Chemicals that the brain makes to keep us feeling content. You add credence to this theory because you said when you exercise that helps you to stay sober. Well of course it does. This is because exercise causes the brain to produce the Feel Good Chemicals and to release them into the bloodstream. The result is you feel better, and drink less or not at all.
So I think you need to get back to your exercise programs. If I was you, I'd make that a top priority in your life. Something like this, eat, sleep, work, and exercise.
Good luck.
