Hey, I have been on methadone for a little over a year now and, I am actually detoxing now. I have never had that type of effect from my dose and the highest I went was to 80mg. In the beginning before I stabilized I felt like I could still go out and get high but, when I reach a point of stabilization I was good.... I never got real hyper actually for me it was the oppisite. If I was up and moving I was fine but, as soon as I lay down or even sat down to try and watch a movie or something I couldnt stay awake.... How long have you been on your current dose??? I have never heard of anyone having those affects but everyone is diff. so you may jst want to talk to the Doc. at your program and explain the sid effects your having.....Good Luck....
I got to a pretty high tolerance like you doing fentanyl patches about 20mg daily with 200mg methadone daily, half the methadone was off the street tho i only got my prescription up to 100. So at first the methadone alone was enough at like 50, then got up to 100, then got more off street while doing fentanyl, to keep up the tired feeling and being high. Eventually everything has to come down. I always felt tired taking opiates until you get so used to withdrawling that opiates give you energy. I'm at 50mg methadone daily now (been 2 months since I was taking all that other stuff), I take split doses and it still only lasts maybe 2-3 hours of somewhat releived symptoms.
So in other words you're tolerance is higher than you're dose. I got to that point and decided I might as well get off the crap since I'm already going through withdrawal permanantly
Everyone reacts differently. I myself get all hyper on night quill. I took about the same amount as you and I do not remember getting hyper but, it was a while ago.
