constantly and never sweat before... will be dripping wet head to toe sometimes 8-10 times a day... long past menopause

I also suffer with excess sweating.. and I'm going through menopause too. I struggle to sleep but I've just got one of those gel pillows. It's not brilliant through the night but its coolness helps me drop off to sleep instead of tossing and turning due to the heat I radiate. I would recommend giving it a try.
Make sure you get a large one which covers whole of pillow because you can try and get a cool area if your area gets warm

I used to be a person who rarely broke into a hard sweat. I have found that my sweating, since being diagnosed, has changed through the years. I too have found it necessary to have extremely chilled rooms. In the daytime 73, 74 degrees and at night I must have it at 68 to 70 degrees. Fortunately we have zones in our house so each room can be set at a different temperature. But, I have found it necessary to have a window air conditioning unit with remote control in my bedroom. I have done this because my temperature tolerance changes throughout the evening and night. I find myself using the remote control to turn the fan hi then down and the same with the temperature. Now I have to put something to redirect the direction of the fan so it does not blow directly upon me . I cannot stand something blowing on me most of the time. I also keep a lightweight long-sleeved front buttoned type jacket close by but I am constantly putting it on and taking it off. Now this is the strange part, it's my upper body that sweats. Mainly my head and my upper chest. My legs are constantly cold. Although I do have to constantly cover and uncover them although never completely. Even a sheet will make a difference. Notice how often we use the word constantly. I say we because I assume that that is the case with most of us suffering from this disease. It is amazing how much more information is accumulating regarding our suffering since we have these forums to share with one another and hopefully the medical institutions. Sorry my grammar and punctuation has deteriorated but I prefer to just talk after a while I cannot deal with correcting everything. Possibly another affliction. Someday maybe there will be a way for us too have a conference via Skype or something where we can all hear one another as though we were together I do miss hearing voices I'm interacting in that method. I don't interact frequently enough so I find myself very long-winded.

I never had a sweating problem before fibro, not just sweating either, cold sweats as well and dreadful chills. I cannot contol my body temp at all

The pain of fibro is what makes us sweat. Try drinking plenty of water.
