It's a fair set of questions to ask.
How long have I been on Suboxone? 4 years, 9 months. It took me a while to calculate this.
I'm dosing 60mcg to 90mcg per shot, and have significantly cut back the number of times I do it per day. I also recently went 26 hours without Suboxone and was able to handle it well the entire time.
I plan to continue tapering although since I was using 130mcg per shot a month or so ago, I'm going to slow down my taper at this point since I have dropped down half way. I've only experienced mild withdrawal symptoms for about a week worth of mornings I'd wake up, only for a few hours each day. Then I felt stabilized after I got down to this level.
I find smoking a lot of weed really helps me in terms of reducing opiate WD symptoms without having to take more buprenorphine. I'm also able to take sleep meds/anxiety meds as needed, so I'm looking forward to a comfortable taper.
Part of me wants to make sure I'll always have buprenorphine on hand because I refuse to let myself relapse on heroin/full agonists of any kind (meaning not just a one time dosage but going back on heroin full time; this is what I would consider a relapse for myself; although I'm not interested in using heroin at all ever again), because I know how bad my life had gotten due to heroin and I refuse to let my life get that bad again. I've been working very hard to get where I am today and I have a lot of hard work left to do in my life, and I can't let heroin become a roadblock in my life.
But the other part of me really does want to be done with buprenorphine; I want to taper to low dose IM buprenorphine (am at moderate-low IV doses at the moment) and then quit when I'm ready to and have the right comfort meds and everything.
I'm hoping by this summer I can make a serious attempt at quitting.
Yes I'm IM/IVing, and yes I micron filter.

Only way I would do it. I wouldn't bother with any other ROA for buprenorphine; I would get to a low enough IM/IV dosage, and jump off completely.
