I am taking it now for 6 days today. I had a rough first couple of days on it. I was nausea-ridden, sweaty. I was having dreams while awake. Ugghh, it was so horrible. Not to mention, It only helps my back for an hour or so. I was even stuttering when I tried to talk. Not cool. Oh, and paranoid. I looked it up, but I'm not sure what it was, allergy or seritonin syndrome. I take 10mg Prozac too, that's all though. The Nucynta interacts dangerously with a whole host of other medications. I hope I can sleep tonight. Anyone know what may cause these symptoms?
