What is Insomnia

You have insomnia if you regularly:

find it hard to go to sleep
wake up several times during the night
lie awake at night
wake up early and cannot go back to sleep
still feel tired after waking up
find it hard to nap during the day even though you're tired
feel tired and irritable during the day
find it difficult to concentrate during the day because you're tired
If you have insomnia for a short time (less than 3 months) it’s called short-term insomnia. Insomnia that lasts 3 months or longer is called long-term insomnia.
