You're definitely going to have to wait it out! Off the top of my head I don't know the half-life of fent, but I know it's up there, plus you've been doing it everyday, so it's built up in your system as well, so research it's half-life first thing, you do have one positive thing going for you though and that's your ROA, if you were wearing the patches you'd have to wait even longer cause there's still residual amounts of fent under your skin for like 24 hours after you take the patch off.... but I tell everyone going from a long active opi to subs, "switch to a shorter acting opi like oxycodone for a week or two before switching to subs so you don't have to wait as long to take the sub" plus it greatly reduces the chance of precipitated withdrawals!
