re: the drunk driving.. I posted that prior to reading more thoroughly that yes you drove after drinking, but didn't feel it impaired you as you followed your drinks with soda. Sorry bout that, fixed my original post to reflect that thought.
That's obviously you're choice if you're here more for friendship advice than anything to do with a drinking problem you're not wanting any help with. I dunno, in my opinion if I had a friend with a drinking problem that treated me horribly when he drank, I might be amenable to continuing a friendship with said friend if he began living in a way that guaranteed it wouldn't happen again.. like no more getting drunk/drinking.. or something along those lines.
