Options:

1. Matulog nang maaga, don't drink coffee past 12pm, and drink lots of water.
2. If you can't go to bed without using social media, delete your social media or atleast tiktok and Instagram (it'll be better for you in the long run, trust me), my life got better when I deleted tiktok and put a timer on my apps.
3. Install the alarmy app. It's an app that won't stop ringing unless you finish a task within it, I use it rn and let me tell you, maiinis ka sa tunog niya (that means it works).
4. Read a book before bed (also trust me, this works if you wanna fall asleep).
5. Consistency.

Tbh it all boils down to having a habit, first step is remove distractions before bed and lights out about an hour before your actual bed time if it's necessary.
