I've tapered off of it the last few months because I have a new PM doc and we're getting to know each other. Tapering off is not a joke, but it's doable (hots/colds, mild w/d). I don't really want to be on methadone for a long time so I'm experimenting with what I can get away with and how it works.
It's by far the best drug I've taken for nerve pain though, so I haven't decided yet. I have several serious spine conditions and my anti-PM HMO requires much hoop-jumping. I'll spare you all the details though. (It makes for a long boring post.)
I get nothing recreational from methadone so I can't give you a conversion to oxy. In fact, I'd say it's the complete reciprocal of oxy. No energy, no effects, nothing but not sick. Which is fine, it's another reason I'm open to trying it.
I just wish it didn't depress my mood so much. It keeps me from being sick and allows me to walk and work. I go from no effect to tired to asleep on the shit. I'm on 30mg a day now, but have gone up to 60mg and down to 0mg (obviously).
* I do recommend having some around to keep you from getting sick. Works great for that even at really low doses.
Background (tl:dr)
It's a long story with this doctor and his Soviet adherence to methadone… (He is Soviet Doctor Building pain Management through Socialism. He looks just like Stalin, same mustache, same pockmarks… I'm looking for Molotov in his back closet.)
The only thing he offered me for long-term pain was methadone. That's it. And I had 2 long conversations in which I clearly stated my fears about being dependent on methadone, the depressive effects, etc. His adamant response is that it's easier to taper off methadone than almost any other PM drug. Mmm-hmm. Thanks.
