This is such a sad story. At least here in Oz, if you can't afford to pay a chemist to dispense, you can go to the government dispensary and they will do it for free. You guys need Medicare like Obama wants. In a country that is a beacon of freedom where you have freedom of speech,gun ownership etc it seems crazy that you can't get medical help when you need it.
Using instead of methadone has to be the worst choice,Bumthat. But I can understand that you don't want to be manipulated by family members either.
I'm afraid I don't have any quick solution for you; you have to sum things up and make what is the best choice for YOU.
All the best,
