I've been taking 50mg tramadol since beginningof Aug-11, 2x4 per day, I had weened myself to 2 per day, and went CT on Saturday, but I can't sleep for any length of time, I got 3 hours last night but was restless all the while. I have no pain or need to take them, I told the anesthatist, I did not want to take pain killers if there was no pain, but he insisted and I feel crap. How long witht the sleeplessness last and can I take any non medical steps to ease the symptoms?
