Methadone withdrawal is known by most people to last for several months--
buprenorphine withdrawal is less severe and lasts for about a month, and people talk as if that is worse than other opiates! I'm not sure if they have just forgotten or if maybe they never experienced real agonist withdrawal. I have seen people come of both, many times, and there is no doubt in my mind that I would rather come of Suboxone than methadone, fentanyl, oxycodone, or even codeine.
