How to overcome chess addiction and associated time wastage &compulsive behaviors&manage academics ?

Q. as stated above.

Set up a specific time for everything. Use app/ website blockers. If that is too harsh, use an app which allows you to access websites for a specific time.
For academics, try to use books as you are less likely to get distracted.

For compulsive behaviours I suggest a mental health forum
