Hi There :-)
Glad to see you posting. Really glad.
I honestly don't know much about coming off liquor.
My first thought here is that coming off liquor AND suboxone simutaneously is not going to be an easy road at all... probably, far, far from it. Truly, I think you need the doctor again and ask about this. Too much at stake here not to have professional guidance.
From reading only, and not experience, it seems that Suboxone is used when both a opiod and alcohol addiction are co-existing. The sub is for the pills, but some have said that it also seems to deplete the craving for alcohol. Please, please talk this situation of yours over with the doctor or an addiction specialist.
And no, I don't think that one drink set you back much at all, if at all.
Wish I could be of more help.
I do care and want the best for you. I will be a cheerleader for now because that is the only thing I can offer. Please stick around and keep us updated, okay?
