There are really two options here;
(a) the fast, short term taper, which is especially good if your habit is relatively small and short lived;
and (b) the longer-term taper to a smallish (1-4mg) dose, followed by long term (6months-several years+) maintenance
The problem between (a) and (b) is that excessive time on suboxone (well, excessive time on opiates generally, but suboxone while trying to quit, when taken for an extended period of time, tends to make this worse) will worsen the post-acute withdrawal issues of anxiety, depression, etc.
What exactly the dosage reduction protocol will be and so on will be up to you and your doc, but I recommend a fairly simple protocol of the first day taking as much buprenorphine as you need to feel reasonably comfortable, and then decreasing it each day, and decreasing the amount that you are decreasing it by each day as well, e.g. maybe 12 -> 8 -> 6 -> (possibly 5) -> 4 -> (possibly 3) -> 2 -> 1 -> .5 -> .25 > .125; another possibility is tapering down and alternating higher and lower doses, like 8 -> 4 -> 6 -> 2 -> 4 -> 1 -> 2 -> 0.5 ... (these are just examples; you may want to go faster; going significantly slower is going to land you in the territory of option (b) being a better choice for you, there is no real official data but I'd say after 2-4 weeks then you risk more serious post acute withdrawal stuff.) The ultra-small doses (0.125mg etc.) will require not only going to the 2mg pills/strips but a pill cutter (or a razor for the strips) and possibly, especially if not using the strips, something like dissolving it in alcohol and using an eyedropper to give yourself microdoses; or snorting carefully cut up lines. Doctors and obviously the pharmaceutical companies don't usually recommend this but I find 2 or even 1mg far too high a dose to jump to nothing from comfortably (although 2/0/2/0 or the like is better than an abrupt drop, the skipping days works because buprenorphine has a long half life), but it anecdotally is a help. Stopping buprenorphine is not easy. Getting on it is easier than people say. The question is whether your doc will want to taper you quickly, maintain you for a long time, or give you a choice. I chose long term maintenance and it is working very well for me. People are different, though; but for me, suboxone is a miracle drug; you may find so, or not, but certainly given the end of the road that serious opioid use has, it's worth giving a shot. But definitely suboxone withdrawal is worse than heroin or oxy (although not as bad as methadone) and this is something to be considered, but a typical relapse situation would wind up with a bit of time on heroin, etc. and then the withdrawal would be as such (honestly, if you have to drop off 8mg of suboxone, say, due to losing your doctor or whatever, it might be more comfortable to switch to dope, although tapering dope for a variety of reasons is very, very difficult, and I wouldn't reccomend it in the slightest unless you live in countries with more enlightened drug policies which have heroin maintenance, etc.) Does sound like suboxone is a reasonable idea for you though. Sound it out with your doc and see what your options are. And your options will be more than that, now, these days there are doctors all over the place prescribing bupe, unlike some years ago when it first came out, even in the middle of nowhere you will probably be able to find one taking patients within driving distance (although many of them are cash-only operations.)
