I took quetapine 25 mgs. the other night and I slept for 5-6hrs. Tha ffg. night I took 25mgs again as my pch has prescribed but after 4 hrs I still can't sleep so I took another 25mgs.at 130am. After 20 mins, I started to feel generally warm, had shallow and quite rapid breathing and can feel my heartbeat thumping, my legs were restless This stopped after 15 mins, and felt good again but I did not sleep until 5am for only 4hrs. I am quite drowsy but unable to get sleep anymore after. Now I am feeling better with just a little headache.Is this normal?or does it not work on me bec. of the unpleasant side effeccts I had last night?.
