Hey Mester
Detox is never comfortable, even with drugs. But the drugs should keep you out of the danger zone. If you feel something is really off call the dr. Maybe they can give you an Ativan taper instead. But its still gonna be a bit rough.
Hang in there you're doing great. I have read so many posts here of people in so much pain, not to mention danger, and they refuse medical help, and ultimately drink. You didn't do that. You took the first step. That is huge!
