Tapering off of fent. Is it possible?

Hi everyone! not seeking any medical advice, but i was just curious: is it possible instead of quitting immediately, to taper down your usage until you are almost down to nothing and then go totally cold turkey to have a less intense withdrawal? do you think that would work? willpower is not an issue. i just want to know if physically it would actually work to decrease the intensity of withdrawal so i can eventually get totally clean.
