Suboxone Alternatives

For the last six months I have been trying very hard to quit taking Oxycontin. Three years ago I was prescribed to take it for a year after a bad car accident and back operations. Its two years past the time my prescription expired and I have basically emptied my pockets trying to get the drug other ways. I was to the point of snorting 200 mg three to five times daily and wound up in the hospital. It was very painful to hear my mother say that she thought she would bury me. I am a pretty discreet person and don't really want to have to miss work or tell my doctor about my problem so I started taking Suboxone because I heard through the grape vine that it helped with recovery.
Recently a friend told me that Suboxone can also be very addictive and I don't want to switch one vice for another. Does anyone know of some supplement that is non-addictive that can help lessen withdrawal symptoms?
