I am 55 and post menopausal as far as I know. I wake up at night at least once, sweating upper torso and groin area. I also feel a panicy( like an adrenalin surge) but I usually fall asleep quite quickly again. I take 1 Isocort before bedtime and 3 mg melatonin or I cant sleep at all. I get what feels like adrenalin surges in the evening starting at about 8 pm. I have read that the sweating could be unstable glucose during the night due to lack of cortisol.Does anyone have any experience of this?
