nootropics/physiology/pharmacology-maxxing general

Got a 45% on my first calc3 exam (integral and differential calculus in 3d space)
I work a part-time job and have neither time nor motivation.
The only solution to this is physiology/pharmacology-maxxing.
Heres the strategy I've devised:
>frequent cold showers to keep up energy levels
>3 cups of black coffee per day minimum
>gorillamind "smooth" and "shroom"
>nicotine
>creatine
>8 hours sleep aided by melatonin
>drinking water constantly
>no-fap for possible testosterone increase
>cardio everyday
>becoming purely egoistic in order to eliminate stress originating from the concern for other people and their thoughts
