I have never taken
methadone, but I did have a big problem with taking opiate painkillers, mainly vicodin. I think the best thing to do is first decide if u are ready to completely stop, including the methadone, since that is an opiate (i think). If u are, I would prepare yourself for w/ds. You may or may not get any, but even if u do, it won't last very long, and in the long run, I promise you it is much better being off these pills.
