I'm glad you are doing well, and YES, forgive yourself, treat yourself well, you made a mistake and learned from it....you will remember it and dredge it up again the next time you are faced with "that little voice that says, you can have just one or two".
i conjure up that very scary image of what I went through the first few days (along with the auditory halleucinations, extreme vomiting) everytime I think how nice it would be to tuck a bottle of Grey-Goose in the freezer and just have "one or two".....
your reiterating your experience did help to bring me back to a stronger resolve, thanks.
