I meant to answer your question, but accidently posted in response to VICourageous, so just read my response to VI's answer.
Yes it will help.
Just make sure you get off the Methadone sooner then later. The Methadone has a much longer life span then the short acting ones, but it is no fun coming off of this med when you have taken a high dose and for too long. These type of pills (all opiates) change our Brain and Body chemistry, so this will take some time to adjust back after you stop. We are here to help you get drug free and see the light.
I wish you all the best.
