Bstrong, I know what you mean about the sweat. I have to flip the pillow 7 or 8 times a night and switch to a different one after about 4 hours. When I wake up, the pillow is nasty wet. I'm not sure if it's the AS or the gh, I just know that if I don't wear a shirt to bed, it feels like I'm laying in a baby pool. The funny thing is, I don't sweat during the day unless I'm working out or sleeping. Once I fall asleep it's like a faucet was turned on.
