My mum has been on methadone for at least 25 years, she was put on it as she was a heroin addict. I am not sure how much she takes a day but am sure it is more than she is prescribed as sometimes when we see her she can't hold a conversation with you and is totally not with it, I know that se also takes vallium. Me and my sisters don't know what to do as we have looked into rehab but just can't afford it!! We would do anything to help her, is it dangerous to just make her go cold turkey
