I too get severe fatigue and not anemic. I've been active my whole life, skiing, mountain climbing, cycling, but I will have days were I go back to bed after getting up in the morning, It seems to cycle.
I was recently on Cytoxan for 6 months, along with Cyclosporine. Since going off the Cytoxan (Cyclophosphamide) my neutrophils have started to go up and down, we think this may are cyclical and the way it just is- to get a better understanding, I just started to go in to my oncologist for blood labs when I feel really tired, a paradox since I don't feel like driving, but we are going to map it out. I am still on Cyclosporine, 200 mg/day.
