Sorry to keep firing the questions I have tried everything tonight to get warn to no avail hot water bottle 2 blankets wearing thick clothing in bed. I can not get warm for love nor money tonight. I'm shivering and my feet are purple. I've always had probs being hypo but for some reason tonight it will not dissappear. I can't put heating on as everyone else is hot and they complain. This illness sucks big time! !
