If you do not have any other medical issues as you have not mentioned any.. you could try proper sleep hygeine methods
1. Avoid caffeinated drinks past 4.00pm
2. Strictly reduce screen time before bed
3. Take a 20min hot shower
4. Consume light food or preferably fruits at dinner
5. Condition yourself with a perfume (I would prefer sandalwood or lavender) by spraying it on your bed while sleeping (can even work as an aromatherapy)
6. Try sleep music to doze off peacefully
Next Steps
If none of the above helps, you will need to consult a psychiatrist for prescribing sleep maintainence pills.
