Just like the best piece of advice you can get is "location, location, location" when considering buying land or a home or renting an apartment or leasing an office or condo, the best piece of advice you can get is "Taper, taper, taper."
You want to taper as comfortably and quickly as possible from the largest dosage you've maintained yourself at, to a more modest dosage.
Then you want to taper a bit slower, to get down to a low dosage.
And then finally you want to ween yourself off the low dosage with very gradual baby steps down from a low dose to nothing.
An example of how I do a taper.... keeping in mind each dosage may be repeated 3 to 6 times per day, IV or IM. If you are doing a sublingual taper (highly recommended over any other ROA if your goal is to taper off), then you might have some diff numbers, I'll give a second example below.
I drop from 130mcg to 98mcg, taking a week to adjust.
Then I drop from 98mcg to 65mcg, taking a week to two weeks to adjust.
Then I decrease by 10mcg, taking a week for each dose decreasement to adjust and stabilize.
Then by the time I get down to, say, 20 to 30 mcg, I'll decrease by 2 to 5 mcg per dosage, until I get to zero (or until I get to a level that is barely being felt whatsoever).
This is going to help reduce the intensity of the withdrawal from buprenorphine significantly. It's very important to taper for optimal success in quitting.
Sublingual tapering example, where the dosages listed are once per day sublingual dosages: (this is the recommended way to taper)
You can start at 8mg per dosage, decrease by 2mg each week for 3 weeks.
At 2mg per dosage, you can decrease by 0.5mg each week for 3 weeks.
Then at 0.5mg, you can decrease by 0.1mg each week (if this is feasible for you), until you get to zero, or until you get to a dose that's barely holding you - then you can jump off.
On the last layer of tapering, going from dosing every day to every other day is also beneficial.
