I don't know about the wd, never done h. I know the stuff I read about Oxy and other opiates did not say "start back at square one" or anything like that. You had a set back. No big deal. Try, try again. DO NOT keep using or you will definitely be back a t square one. Don't throw away all that fucking rediculous agony and have it have been for nothing!
I'm on day 5 with Kratom and am realizing that I am not just going to wake up with no withdrawals one morning and be free. I had been just taking how ever much Kratom I needed to function - sort of. Days 1-3 were in bed even with the Kratom. I went and bought a scale today so I can measure the amount I'm taking and taper down. Hopefully quickly. Ive read a lot of the Kratom mega thread and sounds like there's some withdrawal from it, too. Ugh. BUT, its a shit ton better than what I was up against.
You can do this. START NOW.
For me, and it sounds like you too, is that Kratom is not incredibly pleasant for me, so I should have a pretty easy time tapering. (The hot face, sweaty pits and dialated pupils I'm dealing with seem to be a Kratom side effect for me - fun.)
