Hi Amelia

I think everyone with cancer on this forum will agree with you that fatigue is a major side effect of both treatment and cancer itself also having little enthusiasm to do anything at all including enjoyable activities. I find fatigue is at its worst for a few days after treatment. The remedy for it is gentle excercise, whatever is managable, regular bedtime and importantly getting up time. Good balanced diet, the usual (by plate area) 25% carbohydrate 25% protein 50% vegetables/fruit. Some bright sunlight helps ( I know its winter) and Vitamin D3. Contact with people is important. There is no magic bullet but I find the above helps.
