I just wanted to say that I have experienced a living nightmare with my husband's past and present use of methadone. He burnt everything in our house, sweated prufusivily (can't spell), memory was gone.....got tickets in 6 different counties due to speeding to get to the clinic. Then had to go to a hospital to get off the methadone. Now, again on his third week going to the clinic he has totalled my truck, it rolled 4 times, by the grace of God he survived the wreck. Yes, I do believe Methadone has many side effects. Especially if it is not monitored correctly by the clinic that dispenses it.........Almost a widow........
