[quote=Steve J.] I've lost weight but not so much that I'm at a low body fat percentage - [/quote]

Steve have you had your body fat checked. If you have retained muscle, but lost weight possibly you have lost what your body had in reserve which would be your body fat. Just a thought - I have been freezing since I started chemo in July and just recently found out that I have pretty much no body fat. The weight that I lost during radiation was all body fat because that is what went down. There may be no answer other than bundle up more and keep using that electric blanket.
