Phine4220 please don't make 2 threads that are exactly the same. Also this topic has been extensively covered and we do have a search engine.
It usually takes quite a long time to be able to feel a normal dose of heroin, I wouldn't waste your heroin, what Mass08 said is correct that for most people it will probably take up to 48 days to fully feel the effects of heroin after taking that dose of Suboxone (everyone varies of course, and it also depends on if you were taking the suboxone regularly, but 10 hrs is generally not enough time to feel much if anything).
