It shares many symptoms as Myalgic Encephalomyelitis (M.E.), Chronic Fatigue Immune Dysfunction Syndrome (CFIDS), and may include Multiple Chemical Sensitivity (MCS), Gulf War Syndrome (GWS), Fibromyalgia (FMS), Environmental Illness and Neurasthenia. Neurasthenia, meaning "weakness," is the old name for CFS.  More definitions are here, as well as discussions on the Epstein Barr Virus & Herpesvirus.

Treatment - The management plan that I follow is here.  It discusses lifestyle changes necessary to reverse the symptoms of CFIDS.  If you have it, you can overcome the effects of CFIDS if you detox and come to terms with it.  Many sufferers linger with the disease for 10, 15 and more years.  In the majority of cases it seems that the long term stress and impact on the weak immune system can be overcome by a long term healthy approach to living.

Research - I am currently processing a pile of research papers on this website, particularly on the HHV herpesvirus and Epstein Barr HHV EBV4.

My own story - "I was in Papua New Guines in 1981 for herpes simplex II and caught Glandular Fever, or the Epstein-Barr Virus in 1986. 
I did not listen to my body telling me to slow down, and after continuing with my hectic media career, including two Olympics, the periods of intense fatigue gradually got worse. 
After ten years I began to suffer badly from fatigue and finally began to slow down, but still did not understand the nature of the disease, and worked and played hard.
Fifteen years later and the ultimate crunch came following a period of sustained emotional stress.
CRASH - one year with the main symptom being total incapacitation, asleep for 12 or 14 hours, then up with mental fog and other symptoms before crashing out again a few hours later.
Three years later the recovery has been long slow and painful. I am housebound, being incapable of work or normal social activity.
Memory loss and other symptoms particularly muscle fatigue - living under strict diet and regime of stretching and therapy - has been overwhelming but I have improved recently.
I now realise that I will have this for a long time - perhaps the rest of my life - but, like asthma or diabetes, it is manageable.
