@karenatmayo I did whole brain radiation this past October for breast cancer mets to brain (I also have it in bone and lungs). I am 41 years old.I had almost exactly your side effects. I didnt eat, lost a lot of weight. Spent a lot of time in bed and a few hospital visits. It DOES get better, but takes a fee weeks if not longer after your last treatment. Very important to stay HYDRATED If nothing else. Protein drinks like Ensure, pedialyte or Gatorade all have a little extra for your body. My hair on the other hand hasn't even started to grow back....least of my major worries. Let me know if you have any specific questions. Sending healing thoughts your way.
