Drug Rehabilitation that works

I took methadone recently and i need to know how long i have to wait before i can drink alcohol. Thank you

I took a sip of methadone to stop my withdrawl symptoms, will that hinder my treatment?

If someone has been taking methadone for nearly 4 years, and has been prescribed Subutex and they keep saying they are afraid to begin the Subutex for fear of acute withdrawals but they had their last dose of methadone 51 hours ago and are experiencing mild withdrawal symptoms, would it be okay to begin the Subutex? They keep referring to the half-life of methadone and have a fear of not waiting long enough..any help appreciated.
