Suboxone is a super powerful drug, seriously. Remember that 0.25mg of bupe are equivalent (aproximatelly) to 10mg of Morphine... so 2mg are like 80mg.. and DRs are prescribing doses of 32mg? Like 1200mg of morphine? Are those DRs crazy or what? I think is difficult to have a habit of 1g of PURE morphine a day, and they are prescribing it like candy, I mean, you go with a habit of 1.5g of street heroin a day (maybe 20% of H, TOPS), and they give you straight away 32mg, or sometimes 64?!?!
My point is that you have to try with lower doses maybe, try to make a line of 0.5, I was in 0.5 intranasally for a year or so, first twice a day then I realised that only once a day was better, I was even feeling REALLY euphoric after a couple of hours... Now I'm tappering, 0.07mg today... I still feel if I don't take my daily dose.. quite a lot I mean. I relapsed many times when tapering but then again I start from 0.5 and is REALLY easy and fast at least for me to get to 0.1mg in a week or two, then is much easier to tapper I found, but I got stucked other times at 0.02mg, I relapsed, always, when I go home I fucking relapse. Rambling again... sorry.
My point is (again) that subs are powerful and very very useful if you know how to use them, the trick is to tapper as quick as you can, like try doing half of your dose tomorrow, I bet my balls that you are not going to feel any bad, maybe only a little bit less energy and irritable... Maybe next morning you wake up feeling little WD but then take the same dose as the day before (the other half) and you will feel better again for sure. I know everybody reacts different but my experience and others (for sure many other BLs agree that taper bupe, if you REALLY try it, and if when you can -days off for example-). Also try to keep it in your mouth as long as you can... and swallow the liquid after, BA oral sucks but is something because always there's some bupe remaining.
Good luck dude
If you decide to switch to methadone well, I never tried it to be honest and I had a lot of chances to do it but I was on bupe and I was scared to get those horrible WD when switching from Methadone to bupe, for some people methadone is better cuz they feel that "full" opiate buzz (in the first dose maybe) that they woudn't feel with bupe, nodding and so on, but if you "experiment" with bupe when you are in low doses, for example, if you are at 0.1 and you do 2mg (maybe with LITTLE help of some benzo or other depressants -dangerous mix, remember-) you will NOD and get something very similar to a really opiate buzz. Not the rush of course, because it has to convert to the full agonist norbupe but.. you will get it.
Cheers
EDIT: Maybe you feel bupe different just because is another batch with a new formulation with less of something and more of other shit to make it "better" in some way... I felt something similar once, but here bupes are white and lemon flavoured.
PS (OFF TOPIC): BTW Why the hell they don't make suboxone pills of less than 2mg? Are they crazy? They think is easy to jump from 2mg or what? I wish the Drs to try to jump from a 2mg habit, even a 0.5mg habit you feel like shit for almost 2 weeks... Fucking pharmaceutical industries.. they want us hooked in that forever?
