I was prescribed buprenorphine back when it was only available as a muscle injection. Had previously developed an oxycodone addiction after complications of major spinal surgery, and that was impossible to quit on my own. I tried and tried but it felt like I had sabre-toothed tigers inside my stomach. My then fiance had a friend who'd gone to a clinic for oxycodone addiction and got me the information, and that was a godsend. Used the buprenorphine to wean myself off the oxy, and then used xanax to wean myself off the bupe, and then slowed down the xanax little by little. These days I only take xanax really here or there. Couple of pills a month. I think the whole original process for me took somewhere around one year, give or take. Doctor was actually pretty surprised at how quickly I was able to get through it all, but I think I'd realized quickly when I became dependent on the oxy and it frightened the bejeezus out of me to get help, so I likely caught it much earlier than most. Still, it was bad enough I was willing to learn how to jam a needle into my own muscle. I was still on the injections when I got married. I remember having to lift up my wedding dress to jam one in my thigh right before I went to walk down the aisle.

Memories.
Maybe because I went from doing oxy to the buprenorphine, it never did that much for me comparatively, to get very involved with the bupe. And because I wasn't getting it in pill form, there was more visceral incentive to get myself off it in that it would mean I didn't have to commit violence against my muscles anymore.
Anyway, a specialist or clinic like the one I went to might be the best place to get help getting off the suboxone. I had to pay, but not much as it was partially subsidized.
