I take clonidine for menopause symptons 25mgs bd . I wake in the night and feel really cold inside my body. It's strange as it's inside my body! . It's about 6 hours after I've taken it. It only happens at night. I don't have a high blood pressure 110/70 pulse about 56 without the medication. I'm suppose to take 2 tablets but only take one. Could this be due the the clonidine and that my Bp is dropping when asleep????
