Jake, I don't post much, but I have looked forward to watching your progress. Here's my two cents on the sub issue:
I was very anti-maintenance for a long time. Then I couldn't stop relapsing. I still fought it. Eventually I got a great psychiatrist who didn't prescribe subs, but said maybe I should try maintenance. I trusted him because 1. he's a great doctor and 2. he had no personal stake ($) to me going on it. So I did. I started at 16mg, leveled at 8 for a while, and then 4. After 4mg for several months, I started taking it every other day, and then every third day. For about 2 months I took 2-4 mg every three days or when I felt even slightly sick. At that point it apparently was all psychosomatic, because I just stopped about a month ago with absolutely zero withdrawal. I wanted to go into a trauma recovery program where you couldn't be on narcotics. Absolutely no problems. I was on it for about 9 months.
YOU CAN DO THIS! Take whatever you need to not feel sick! That feeling will drive you to use. Certainly use the lowest dose possible, but you don't need to feel bad. Don't punish yourself. Stay clean from the dope, take your subs, and worry about getting off them after you've stabilized for a few months. Fuck what the doctor says if you don't trust him, and find your own way to taper. It is possible to do it painlessly. It's quantity, but also frequency. It won't be long before you can skip days and feel fine.
Just my 2 cents. You should be proud of yourself. It's hard letting go. But it's time to have a meaningful life, and you can do it. You are already on your way. Best of luck.
