I use oxycodone/percocet for chronic pain at times and as long as I space them out it works for me, but I also don't take a huge amount of kratom compared to some for chronic pain. I alternate them. I haven't experienced withdrawal from kratom when I switch to the meds or vise versa, however it's not the best way because we're still exposing our receptors to opioids daily either way. I also use hirsutra and Javanica to taper down kratom for easier transitioning. What kind of withdrawaling are you experiencing and what is your dosing like for kratom. I find that the pain meds don't work as well if enough time isn't given between them and kratom.
