Yeah^ that could be true but I kind of doubt it 10 grams of headshop quality Maeng da completely eradicated my withdrawal symptoms fro, a heavy and daily 2+ year IV heroin habit, though it should be said I had been kicking CT for four days, so my body was kind of in shock and probably worked out for me better because of that, my suggestion would be to try and wait as long as you can before taking it, maybe use some benzos and clonedine to ride out as much discomfort you can, and then try the Kratom, I'd start with 10 grams and go up from there if you had a fentanyl tolerance, I doubt that 10g would be too much in terms of negative side effects. IME (which I should note is severely limited when it comes to Kratom) it seems like any other opiate in that as long as you got the tolerance, high dosages aren't going to make you feel sick unless they are too high relative to what you can normally handle. I don't think it's like, if you pass 25g's you're going to suffer unpleasant side effects despite the fact that you're coming off say, 600mg of methadone, but please correct me if I'm wrong cause some drugs do work that way (like tramadol will always seem to have me feeling like shit way before it can cause enough agonism to really relieve withdrawal syndromes).
