Many people, myself included, end up on an endless treadmill of switching to suboxone or kratom to quit a full agonist, then being unable to get off due to the protracted withdrawal and figuring we could switch to a shorter withdrawal drug to get off. And then switching back to the others, ad nauseum. I have never been able to do it, not once. It makes sense in theory, but in practice, the effort is Herculean. You're better off tapering down the suboxone to a few low dose and then jumping off, and jumping right into working out, and use gabapentin or Lyrica to help with the transition/relatively light withdrawals. I HAVE done that several times, and I have also done cold turkey several times. Those have been the only times I've been successful for any length of time.
