Gail - I went to the link you indicated and got a "page not found" error msg on the NCI page, but a search on the same page for the L-carnitine and the trials yields info at the following link:
http://www.cancer.gov/clinicaltrials/ft-ECOG-E4Z02

Bonnie - my son who completed tx right about the same time your daughter did, is also experiencing fatigue. Maybe the L-carnitine or having thyroid checked would be something for us to look into.
