Just a few questions.
Have you been abusing your methadone?
I am trying to figure out why your family is up your ass about it, besides possibly cost of maintaining your methadone.
From wherever you stay to the clinic, is the distance so far that you cannot get there any other way?
I don't know how this would work, or if a hospital even offers it by you, but Methadone is a NMDA receptor antagonist. Ketamine is also a NMDA receptor antagonist.
Ketamine is used in a medical setting for chronic pain patients and depressed folks as well.
Part of Ketamines method of action, resets pain receptors in your brain. If it is offered by you, that might be an option.
I'd read Loperamide mega threads before starting it as a taper.
Also read any methadone threads and see what may help.
Even if you have to make a deal with family, try to taper your dose as best you can.
As always, YMMV.
