Insomnia

Insomnia, also known as sleeplessness, is a sleep disorder where people have trouble falling asleep or staying asleep as long as desired. It can occur independently or as a result of another problem. It is a common symptom of ME/CFS.

Presentation
Insomnia is present when a patient finds it unusually difficult to fall asleep, maintain sleep, or wakes up early in the morning with an inability to return to sleep.

Insomnia can cause many secondary symptoms and problems, including daytime sleepiness, feeling unrefreshed after sleep, irritability, anxiety, low energy, and depressed mood. Long-term insomnia can result in muscle weariness, hallucinations, mental fatigue and double vision.
