17M, diagnosed with OCD and ADD.

Well, i got into huberman shit. He said that "rewards" are bad etc etc. It got to the point where i was studying for 11-12 hours and didn't reward myself, and got anxious if i had to eat something sugary because apparently my brain would make it as a reward etc.

The argument that my brain gives, is that huberman gives stuff out from his research, so statistically it should be true for me for the majority of time right?

Is optimizing every single thing better or is being stress free relatively better if you wanna get at the top of your field? (i'm into mathematics)

I seriously want to unlearn everything that i learnt from huberman.
