How is fatigue related to multiple sclerosis?

ANSWER

About eight in 10 people with multiple sclerosis (MS) feel very tired. It often comes on in the afternoon and causes weak muscles, slowed thinking, or sleepiness. It's usually not related to the amount of work you do. Some people with MS say they can feel tired even after a good night's sleep.
