Good Morning:

To improve energy or reduce fatigue, I would try acupuncture administered by a Chinese Medicine practitioner. If that is not an immediate option, soups made with bone broth or pure chicken broth can help. (Please don’t think that canned soup will do the trick). Make or buy the real thing—preferably organic. If you eat meat, bison is exceptionally rich in nutrients. A couple of bison burgers now and then will help boost your energy. These are a few things you could try.
It is wonderful that you are keeping up with daily walks and Pilates. Don’t worry about hitting the couch in the afternoon. After all you are doing an intensive medical treatment and you can expect some fatigue from all that your body is going through. Take care and try to eat organic and low processed foods!!! Best wishes.
