mixing methadone and orphenadrine**need advice

Currently on methadone maintenance treatment in Canada, and have been on the program for 4 months. Experienced drug user, I understand potential risks with combining drugs with methadone, but I have recently purchased a handful of Orphenadrine (100mg) pills, and i have been experimenting with combining low doses with my daily 75 mg/ml drink.


I'd like it if anyone could recommend the best time at dosing the orphenadrine(or best dose) with the 'done to achieve euphoria. Last few attempts have been considerably enjoyable but if anyone could recommend the best timing for mixing these two substances. don't worry, i'll play safe i just need someone to chime in with personal experiences/knowledge if possible.
