they cut you off the opiate, and the methadone works as a synthetic opiate
, preventing the first stage of acute withdrawal
. every day they decrease the dosage
of methadone, until the final day you walk out clean and sober from the opiate and the methadone. i went in on 300mg of oxycontin daily, and it took 8 days for the methadone tapering, and i walked out clean. it's a very comfortable withdrawal. the symptoms vary.
