Grendhar, I'm sorry that you drank and that you feel low right now. Don't feel stupid, just come up with a plan so it doesn't happen again. Getting 8 days sober was great, and you can do it again.
I found that changing daily routines in the early days helped me. You could try driving home by a different route, shopping in a different store, etc. For me, I think it helped to shift the thought patterns of drinking.
