How long does soboxin stay in your system?

From what i understand, my Dr. has informed me that soboxin can stay in a persons system up to ten days depending on the dosage a person takes and how long you have been taking it. I have personally been on soboxin since July 2008. Dosage varies from person to person. My original opiate was methadone and percocet for several months. Soboxin has totally helped be opiate free. In the next few months I would like to get off soboxin also because it is costly if you dont have insurance. Also, it is an opiate base drug, used for chronic useres of opiates.
