Way to go on getting 7 days! I have to agree with Dee on the willpower thing. I think when I finally realized I had no willpower when it came to alcohol, I was able to accept that I was going to have to find help/support (like you're doing now).
I know what will happen if I pick up a drink. I won't be happy with one (or two or three, or only one night of getting drunk). I was scared to stop and scared to keep drinking.
Things really do get better, though, so hang in there!
