Done that many times
I've hit 100 days a couple of times now and thought - well, maybe just once... well, maybe just wine... once a month? Saturdays only? On my birthday?
I try to ease back in and within a week I'm back to 1/3 of a fifth of vodka a night. I'm running out of options and starting to get into my head that for me there's no halfway measure, but I'm still fighting it and mourning it, too.
