Yeah truth to above two posters, maybe the first time u go into w/d its 3-5 days, but for a seasoned user whose w/drawn before, I'd say you feel true physical symtoms for 7-14 days. Sure you feel the worst the first 2-5 days, but you don't just have a switch go off and feel normal on day 5 or day 6 or whatever. You're not puking and writhing in agony on day 6, but ur sore, achy, sleepless, maaybe still getting hot/cold flashes, nausiouss....all in varying degrees and not all the time but they're there.
That said, I still don't get what the OP is suggesting. The proposal only makes sense in light of a relapse, and if that's the case, then the detox should be medically supervised again.
OP, pls ellaborate on your situation and what your hoping to accomplish. Or are you posing a hypothetical question?
Also, can you explain the difference between naloxone and naltrexone in terms of effect?
