I do agree with Flyin'Dutch': "ME is a complex syndrome which is poorly understood. That goes for possible cause, diagnosis and treatment."
More to the point, Chronic Fatigue Syndrome (CFS) is a persistent, long-term tiredness; Myalgic Encephalomyelitis (ME) stands for muscle pains and inflammation of the brain and spinal cord. Not every CFS is due to ME and not all (although most) cases of ME are accompanied by chronic fatigue.
So, before deciding on a treatment you have to figure out what is responsible for your particular case of CFS: it can be virus; depression; PTSD; mental stress. Don't let your GP to fob you off with a few antidepressants and amphetamines, insist on a treatment of the root cause of your problem.
