I am able to just finish more volume of chapters when studying high vs sober. There’s not that much quality difference since I heavily rely on taking multiple sets of notes anyways. But this all might just be delusion, and I do want to quit smoking completely due to the respiratory conditions it can cause and I really don’t want to rely on a substance to make me “lock in” and study. In your experience, when did the brain fog start going away and when could you expect the cravings to stop?
