hi
I understand your query.
sleep wake cycle disturbances can lead to various problem in daily routines.
You have sleep fragmentation and require strict
sleep hygiene management.
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 coffee soft drink at night
Use bed when you feel sleepy,read up to when you will sleepy
No talking or use mobile in bed or watching Tv or playing games while you are in bed.
Calm and cool bed room
All of this will help you to restore good sleep
Besides this there are some medicines like benzodiazapine and zolpidame which are useful in treat sleep problems but before that you have to do consultation and get help.
I hope i have answered your query.
happy to help you further.
Thank you
