I have Fibromyalgia, and also suffer the night sweats due to all the wonderful hormones & medications I'm on. However, I've gone the route of minimizing the experience by adapting to the problem, rather than playing with the medications.
I keep several sets of bamboo sleepwear (no cottons), use bamboo sheets, have 2 full size body pillows, and just recently switched to a memory foam bed that is supposed to "breathe". And, of course, the room is kept cool. The bamboo doesn't collect moisture, it just passes it thru. So for minor "sweats", you don't need to do anything. If you have a "puddle" night, then I just swap all my sleepwear for a dry set, swap to a dry body pillow, and if needed, put down a fuzzy waterproof (on one side) throw to cover the wet bottom sheets.
I also have a strange little device called a bed fan, which actually blows a variable stream of air between the sheets. Wonderful to cool off or dry off. If you have money to spare, you could try something like: http://www.activeforever.com/p.....opper.aspx .
Re-reading your message, perhaps this info won't help you... You wake up soaked. I don't sleep much at all, so I awake the moment I start to get "warm". Perhaps you should get all your hormone levels checked, if you haven't already. Male or Female, a hormone imbalance will make the "night sweats" worse. You might be able to make some adjustments to at least minimize the problem...
