Book excerpt: Some doctors still think Chronic Fatigue Syndrome is a "fake" diagnosis. In this book, Joel Young, MD, presents the research, experience, and treatments that prove otherwise. Millions of Americans experience chronic fatigue syndrome (CFS), a continuous exhaustion and a feeling comparable to that of having just run a marathon when all they have done is a daily living task, such as taking a shower or getting dressed. Doctors don't have tests for CFS, and some think it's a faux or psychological disorder. Joel Young, MD, in this heavily researched book, explains why it is a true physical illness and how it may be treated. He details how he successfully treats the symptoms, which can include severe fatigue, "brain fog," chronic pain, and sleep problems. Unlike doctors who recommend exercise, supplements, or opioid medications, Young integrates such options as long-acting stimulants, meditation, and dietary changes to reduce fatigue, as well as non-opioid drugs, medical marijuana, and self-help options including yoga for the associated chronic pain.
