ThnxSince Fentanyl has such a short half-life, I'd suggest not taking anymore Kratom and wait for the Fentanyl W/Ds to kick in. Im sure you can handle a few hours of W/Ds before taking the Suboxone. If you don't, you may very likely end up in precipitated w/d's and thats going to be 10x worse than waiting a few hours in W/D before taking the Suboxone.
