I personally found no amount of tapering, even when the schedule was stuck to, made the withdrawal
any less uncomfortable/painful.
I went from 32-40mg/day of sublingual Buprenorphine, tapered to 2mg every other day over the course of 1-1.5 months, then to 1mg every other day after about a month. There was no discomfort during this period
, from 40mg a day to 1mg every other day. Buprenorphine is very easy to taper down with, at least I found it to be.
