Hello. I am a 64 year old female and for a couple of years (or more) I have had insomnia and excessive sweating from hot flashes. Probably four or five every day and during the night I have lots of sweating. I am post-menopausal. I take levothyroxine for hypoactive thyroid and have been for years. When I have the hot flashes during the day my entire body becomes wet. Legs, everything!! I have a combipatch but it really does no good. I have tried Black Cohash. My doc gave me trazadone (100 mg) to take for the insomnia but I had to quit and it was making me very confused. I also had extreme muscle/joint aches during the time I took trazadone. Initially I took 50 mg and it did not help the insomnia. I believe that when she raised the dosage to 100 mg it helped the insomnia but that is when I became confused and quit taking it. I mention the levothyroxine as I have read articles that indicate excessive sweating, insomnia, and palpitations can be caused by this. At the end of my rope. Thank you. Luann
