I was very tired too after radiation, it's when I napped the most! But have noticed that on chemo now on the fourth cycle, I am starting to get more tired. I think the chemo has similar effects...as well as some nausea for myself, to radiation. They told me it would be hair loss in the area being treated which was my left frontal lobe, whereas I lost a bit more than that, but it seems to be slowly coming back. I have had two scans since radiation finished and there has been no movement on the tumour (or what's left of it) and radiation made an improvement. My chemo is a trial drug and I do 5 days on out of every 28 and MRI's every three months.
I also think there will be lots of new things around for us to try 🙂
