The best advice for dealing with insomnia is to only use your bed for sleeping.

Avoid activities like studying, watching TV, or using your phone in your bed, as this can disrupt this association and make it more difficult to fall asleep. Avoid taking sleeping pills unless prescribed by a doctor, as they can have harmful side effects and may not address the underlying causes of insomnia. Going to bed at different times each night can also disrupt your sleep cycle and make it harder to fall asleep.
