There is now a generic form of Subutex available now, and most pharmacies retail at $3 per pill, still costly, but if you can get your doc to change your script to subutex, and you work on lowering your dose it can totally be done. Suboxone
is not yet available
as a generic
as the pharm companies are having a hard time getting the Buprenorphine/naloxone combo to dissolve the right way, but it is in the works.
Also, have you tried lowering your dose to say 8mgs?
