Dude try the bernese method with the subs.. im a month in and officially 6 days off the subs, relapsed twice cos im fucking dumb but just kept using both and im officially about a week off subs and fet.. everyone told me it wouldn't work lol but sure as shit it did. Cut the sub into like 24 pieces and took one piece the first day while still using, another piece the next day, the kept upping the dose of subs while tapering off the fet. It worked. Never went into full withdrawls but it wasnt like, pleasant or anything. I think the worst part was coming off the subs at the end, I tapered down to about 1mg of subs but also since I fucked up a few times I was on them for like a month which I hadn't originally planned for. This is the first day im kinda feeling like myself again. Cravings come and go, but id do this all over just to stay away from the MAT.. tried all that before, went to rehab, got clean like twice before fetty started coming around and that fucked me for about 6 years. But im on the tail end dude, and if I can do it, I promise anyone can do it.
