(HealthDay News) -- Chronic fatigue syndrome is characterized by extreme fatigue that makes it difficult to complete life's daily tasks.

It has no known cause or cure, but the National Women's Health Information Center says you can take steps to help manage its symptoms:

• Keep an activities journal, particularly on days that you feel especially tired.
• Look for patterns in your symptoms and eliminate or reduce activities that seem to trigger them.
• Work with an occupational therapist to help you conserve energy and feel better.
• At the end of the day, evaluate how much energy you had, compared to how much energy you needed to use. Doing so may help you better manage your energy.
• As needed, take over-the-counter pain relievers and antihistamines that don't cause drowsiness.
