My wife has had chemo for brest cancer, but what is fec chemo? do you mean after each session or after the complete course?
My wife had chemo monthly for 6 months, felt really tired for the first two weeks or so of every session, and just when she was beginning to feel ok, it was time for another dose, but once the 6 months was over with she recovered really quickly, are you having chemo yourself or is it a relative? whatever it is I wish you real good luck, keep smiling and keep your sense of humour, it does help, Ray
