You are playing with a technique called ( The Drunken Boxer ).

It has taken me a lifetime to master. In this technique you must know yourself and your poison. Everytime is different. Not enough or just toooo much will throw you so far off it's maddenning. Do not mix poisons untill your a master. I still do not mix. If you are taking scripts and smoking then your just getting stoned like the rest.

My advice is to get stoned after class.
