Hey, Mike, it happens. Probably most of us have made many starts and restarts, me included.
I'm glad that you were able to break free for a week! That's a whole week when you were not polluting or harming yourself with alcohol.
But alcohol IS an addictive poison that degrades your mind, health, emotions, etc. -- all the more reason to keep trying to break free of it.
Please don't beat yourself up over this -- it's counterproductive. Better to have an optimistic attitude and add more strategies to get free of the snares of addiction.
Still wishing you the best!
