LOL ... smoking good stuff has never been helpful in perception and control on the battlefield, but for visualizing exercises it can offer perspectives that the unaltered mind would never have considered.

Indeed, excellent advice Sasaki. I tend to do this while in battle (well, before the thick of an an engagement, when assessing possibilities and probabilities etc.). Developing the ability to visualize rapidly while maintaining awareness of what's actually going on at the same time is an invaluable ability in any game (or real-world scenario) like these.
