Yes you can do it the way your taking about but whats to stop you from abusing the heroin again.It takes the brain time to change back chemically from were it was before you started abusing heroin.That's why the doctor likely wants you on it for awhile.What kind of support system do you have,are you working ect.It's very important that you break away from the old lifestyle and all the people you associated with.If you can do this without the
suboxone then that's great but you might want to think about it.As soon as you have your first bit of stress you're going to want to use I can garuntee that,that's why it's nice to be stable on suboxone so you can get yourself straitened around and get your life back on track before going totally clean.Good luck to you.....Dave
