Tolerance to methadone increases slower than any other narcotic. I have seen people go years w/o a dose increase. 70mg is a moderate to large dose. I wouldn't expect a need for an increase for a year or two. Having BT meds w/ 'done is rare! You have a "nice" doc. I would suggest switching to Roxane's methadone, as it is FAR SUPERIOR. This was verified by many BTers in the old forum. The pill is 1/3 the size as well and maybe cheaper. Mallinkrot meds or horrible IMO. Most docs will have an ECHO/ EKG done during TX w/ methadone to monitor its' potential for heart problems. Good luck. E
