i can understand wanting to iv subutex, i really can, but suboxone i dont, they deliberately put naloxone in it to prevent addicts iv'ing the tablets, its supposed to induce instant withdrawal when iv'd but if it doesnt do that for you then fair enough.
i do wish you the best of luck for the future an hope you get shit sorted out, you sound like your on the right path.
one thing id have to say though is drugs are not bad for you, but prohibition is. a lot of drugs are actually medically benign in their pure form especially when used with due care and responsibility including heroin (with the exception of a few). all of which cant exist because of prohibition. and those few would probably would not exist now if the trade had been regulated properly.
PROHIBITION?? - just say NO!!
