Few medical problems are surrounded by as much ignorance and prejudice as Chronic Fatigue Syndrome (CFS), a diverse illness of uncertain origins and indeterminate duration. Often unfairly dismissed as the "yuppie flu", this devastating condition afflicts increasing numbers of people throughout the world. This guide is written from an unusual perspective - the author is a doctor who himself suffers from CFS. He is therefore able to write from first-hand experience about the difficulties, frustrations and uncertainties facing those with CFS.
