I've tried several times on my own, especially in the begining, I think I was in denial about my physical dependency. I would spend several days in bed until I just couldn't take it anymore. Then I tried tapering off, but just could never seem to get below a certain amount, about my present amount. Then my first attempt at a clinic was a disaster, first the intake nurse thought i was a liar because i said i didn't use intravenously, then she needed me to give urine,  I have a shy blader, and the more pressure I feel the less likely I'll be able to go. Came back the next day, waiting in the waiting  room with my eyes closed to keep calm, the director saw me and assumed I was "knodding out" and asked me to leave. I since returned about 6 months later, got started on methadone, but started to educate my self of the heart problems that can be a risk factor, permanent heart damage... no thank you.
