Rewards during a reboot

I'm looking for rewards suggestions, rewards for myself for small tasks during the day , i'm a medical student and have looooots of studying to do, and my brain always asks for porn as a reward, we need those circuits rewired, so what do you suggest as multiple trigger free, non expensive, not very time consuming rewards for the small tasks of the day, and also what about big rewards for like after a big test or a week of stress and work .. appreciate the replies !
Stay strong brothers

 

Thanks for the encouragement man, i'm really inspired by your journal by the way ..
I figured out that taking 10 or 15 mins walks eases me out a lot and clears my head, also reading a book that i like in break times, stretching a doing few push ups also energizes me (makes me feel like a stud, lol), very selective content of youtube can work for me as well .. i'm still learning how to fix my diet, i hope i get around to that soon and really eat healthy, because actually i enjoy it، it's the task of shopping and preparing for meals and snacks that i procrastinate on ..
As regards to the social media tip, i'm doing that too , i've delete it my Instagram account for good (i don't need that shit) and also deactivated my Facebook because a lot of my college news is posted there so i can't delete it unfortunately, i limit my youtube usage to music and nofap videos and cartoons , and that's it ..

I'm really looking forward to expanding my rewards spectrum, and replacing all my bad habits that ultimately lead back to escapism and porn ..

Wish me luck @ZenPhysics !! And good luck to you as well !
