If you get off subs, you won't be truly well for a year.
Honestly, I think using subs can potentially be a net positive for your life. Using subs correctly could improve your life more than if you went without.
So here's what you do: first off, get switched to subutex, if you can. Say the suboxone is giving you migraines that are stopping you from being able to work.
People commonly say that the naloxone has no effect, but this is wrong. They say that because the bup has a higher affinity for the mu reecptor, the naloxone has no effect. While it is true that bup has a higher affinity and will outcompete naloxone, what they don't realize is that at doses of 32mg of buprenorphine, there's still 20% of the mu receptors untouched, which can and are bound by naloxone. At doses of 8mg it's like 30%. So yeahx subutex is better, we also ha e double blinded studies unanimously showing bup is preferred to bup/nal.
Okay, so switching to subutex is important (it's also much cheaper). Secondly, start lowering your dose .
Many, many people report horrible side effects at high doses, no high or euphoria, and the lower they get the higher they become. Bup is used at doses of 50mcg (0.05mg) for pain management, so it's very effective.
Start lowering your dose by .25mg-1mg a week. Honestly you could likely just drop your dose from 8mg to 4mg in the first week pretty easily. Tapering only becomes difficult at lose doses. First week drop from 8-4, second week from 4-3, 3rd weem 3-2, 2-1.5, 1.5-1.25, 1.25-1.1, 1.1-.9, etc. Every week see where you're at. I'd drop to around 3mg and see how you feel. If you start feeling happy again, I'd recommend just staying there. If you want to quit completely, tapering is your best option anyways, so you'll have to taper regardless of of you want to quit or try a lower dose. But I'd recommend getting below 4mg and seeing how you feel, you'll probably start feeling a glow and euphoria again, which isn't a bad thing. Hope it works out.
