But it is important to find out cause behind insomnia.
Most common causes are

2.Anxiety
3. Depression
4.physical illness.
Need to evaluation and if any then treatment of it is necessary.
Sleep hygiene is very helpful to restore sound sleep.
Certain routines and lifestyle modification will help you like
Fix sleep schedule and stick on it/no day time sleep
Exercise that makes you fatigue
Stress free activities and meditations
Avoid alcohol and smoking/avoid heavy meal in dinner/avoid tea cofffee soft drink at night
Use bed when you feel sleepy/read up to when you will sleepy
No talking or use mobile in bed
Calm and cool bed room
all of this will help you to restore good sleep.
Treatment of underlying psychological problem can also help.
Besides this there are some medicines like benzodiazapine and zolpidame which are useful in treat sleep problems but before that you have to require consultation to
psychiatrist.
Get well soon
