I am waking up around 4 hours after I go to sleep, very hot and often with itchy skin. It then takes me up to 3 hours to get back to sleep. I am waking up intermittently before this also and think it may be due to the heat. I have altered my bed to be more breathable but it has not helped much. I am on Tecfidera which I know causes heat & flushing but even when I come off it for a few days I still get the heat intolerance at night. Usually the 1st half of the night not the latter. Has anyone experienced this and if so is there anything they helped.
