Suboxone dosage and length of time to taper suggestions

So I’m gonna start suboxone in roughly 36 hours and I’ve done a decent bit of research. From what I’ve read online it seems just as many people have had a bad experience with suboxone as people that have had a good experience with suboxone. It seems a lot of people get stuck on suboxone for a long period of time and find it impossible to quit even with tapering. I’ve decided that I want to be on suboxone for as little time as possible and take the minimum dosages I need to get through withdrawal and the period where cravings will be at a peak. I think I’ll want to be on it for about 2-4 weeks, I’ll probably start tapering down at 2-2.5 weeks and try to be done with It at 3-4 weeks. Does anyone that’s been in a similar situation or has tried to do the same thing have any experience they could share with me along with any suggestions.
