I think that once you stop the kratom your w/d will be very mild. I did something similar but with bupe and tramadol. Both tramadol and kratom are much weaker than bupe/methadone. I had a really hard time getting off the bupe from a small dose. But after being on tramadol for 3 weeks I barely had any w/d symptoms. They really were nothing compared to previous w/d. I was really surprised how well this stepping down method worked and how painless it was.
