Hello circles5: The Skeezyks doesn't drink anymore. It's not because I wouldn't like to. Actually I love the taste of almost all alcoholic beverages. (Except I'm not a big beer lover.) But whenever I've gone on med's, in the past, I've stopped drinking while I was on them. And now, I'm on a fixed income & can no longer afford it. Water is cheaper....
There was a time, many years ago now however, when I was a big social drinker. Plus I would binge drink whenever I had some sort of problem, such as if something went seriously wrong at work. (By the way, I have also always struggled with agoraphobia.) So I think I have some understanding of what you're experiencing.
Anyway, it certainly wouldn't hurt for you to try out an alcohol treatment group. You obviously don't want to keep having experiences such as the one you describe in your post. There's certainly nothing wrong with a 2 1/2 hour walk at 3 a.m. I do it sometimes when I can't sleep. But I just do walking meditation around my house... where it's safe... I wish you well...
