I'm on Bupe maintenance, for a year and a half now. I imagine buprenorphine withdrawal would be very similar to methadone withdrawal which I have cold turkey'd a methadone withdrawal 2 years ago. I cold stopped at 130mg liquid a day at a methadone clinic I was going to. For financial and other reasons I was forced to cold detox 130mg Methadone. It took 3/4 days before withdrawal set in, a month of acute sick withdrawal, another month of post acute withdrawal symptoms. After the 3rd week I went into a detox where I was given subutex for a week, I felt great while in detox but had no idea 48 hours after I left detox and the last subutex dosage I went back into withdrawal. I imagine buprenorphine and methadone to be a similar withdrawal in regards to the length of withdrawal time, possibly buprenorphine withdrawal symptoms may be less intense than methadone, but I don't think by much.
