which brand of methadone works best? roxane vs mallinckrodt vs otthers? please help. also i am currently on 90mg of methadone and 40mg of hydrocodone per day for chronic pain. in actuality i need about 180-200mg of methadone to cover all my pain. is there any other pain killer that may work better than methadone? should i tell my pain mangt dr that i need a higher dose or do you think him finding out that i actualy need twice the amount he is giving me may bother him or cause problems? any help or advice is greatly appreciated.
