My sister has been on methadone for about year now. Her drug problems started in high school, but escalated after a fall for which she was irresponsibly prescribed an abundance painkillers (at one point her doctor gave her a 3 week supply, she came in four days later saying she was out and he gave her 5 weeks worth). The same doctor has since prescribed Ritalin and Xanax for her. My common sense tells me something's not right with that mixture (Ritalin, Xanax and Methadone).
