Who else can't sleep?

Layers, layers, layers...that's the trick. Thinnest layer first, sheet, then thin cotton blanket, (like the hospital ones with the little holes), then a light doonah. Later in winter add a heavier blanket folded at the foot of the bed. Dress very lightly, and not in synthetic. Add and subtract layers as necessary. I also had the most horrendous night sweats, sometimes changing both me and the sheets up to four times a night. Terrible...
