I do over masterbation, tell me some veg diet

I’m 20yrs old boy…
I do over masterbation 2 to 4 days in a week, and I cum 1 to 4 times in a day…
Feel little pain in brain while studies…
Some time I feel too much power to do or
Feel so tired quickly and most of the time…
Plz tell me how I can control my lust…
And some veg diet…
Thank you!
