I purchased a single bed wool all season package to try and reduce the heavy sweating encountered each night. The first couple of nights were brilliant, nice and warm but no sweating. However I caught a bad cold shortly after and have been sweating at night again, though nothing like before. The wool definitely works and I am sure once the cold has passed dry nights will return, can't wait. The only down side was the wool pillow, I know pillows are hard to adapt to at first but it was really hard, I tried it for about four nights but have returned to my old one, again the bad cold I had did not help with constant headache. I will not give up on it and will try again when the cold has passed.
