Yes I have read all of your posts, and I am very aware that one can be dependent on a substance without being addicted, and vice versa.
I was on suboxone for 18 months, didn't get high on other opiates aside from one time, was in outpatient treatment that whole time, and after completing it I went away to school, detoxed off the suboxone there, and guess what I did a few months later? I got right back on the H train. Luckily it was just over winter break, and I left it behind when I went back to school, but I continued to relapse sometimes when I would go back to my hometown.
So when it comes down to it our situations are pretty similar, so I was talking from personal experience after reading all of your posts. Things are a lot different once you are off of the maintenance drug, even if you don't think it now. I barely even thought about drugs when I was on suboxone, and it was really easy for me to go a while without any cravings at all. Something just really changed once I got off the suboxone. For a little while I felt better (after the acute withdrawal of course) but then I went on a binge over winter break after having a few months off of the suboxone.
Treatment is good while you are on a maintenance drug, and I hope you can stay clean once you get off the methadone, but take your treatment seriously still when you get off of the maintenance drug. Just don't think that you can predict how you will feel once you stop taking the methadone, even if you feel that the methadone never really worked well for you.
