I agree with Nuudawn. Your post is almost as though you are resigned to relapse,you expect it even. Areyou looking to do something different this time? Is your bf preventing your recovery.I don't know how the brethalyzer in car thing works but not sure how this would prevent you from going to meetings?
I know Dee always says if what we're doing isn't working it's time to try something new. Maybe WFS or SMART or indeed individual counselling,as others have suggested
