The best book for people about to take ketamine is Programming and Metaprogramming in the Human Biocomputer by John C. Lilly, who was the ketamine guy in the same sense that Leary was the LSD guy and McKenna is associated with shrooms.
Seconding everyone posting about psychedelics. More scientists and mathematicians should be taking them. My personal recommendation would be 1/3 of a gram of MDMA every 3 months, or month if you feel even a little bit down in between. Do it in a friendly setting with someone you like. If you don't come out with deep love and respect for them, yourself and humanity in general, mushrooms.
Mushrooms are very good for feeling positive about the planet, also.
