Fatigue during or after cancer treatment is due to a number of causes, and sometimes seems to have no single "cause." You may wish to consider supplementation with l-carnitine, which facilitates fatty acid metabolism -- it has been found in preliminary studies to relieve "cancer fatigue" in some patients, esp. those who have received cisplatin chemotherapy. e.g.;

British Journal of Cancer (2002) 86, 1854-1857.

Potential role of levocarnitine supplementation for the treatment of chemotherapy-induced fatigue in non-anaemic cancer patients
F Graziano et al.

There are a number of other papers and some NCI-supported clinical trials ongoing.

L-carnitine in liquid form is available from GNC -- Barry took it throughout and maintained good energy levels considering, and bounced back to normal actvity levels pretty quickly. We suggested it to another Hopkins patient who had been saying "she could not get out of bed" and she reported that in a short time she felt much more enegetic. Just a couple of data points and thus only of anecdotal interest, but still..seems to be more than just "snake oil."

(Thus was OK'd by our doctors, of course --)
