Focus

I'm researching how various substances and techniques effect focus (and to a lesser extent energy/will).

Substance

Caffeine

Decent boost. 30 minute delay. I've built up a certain immunity.

Technique

Nap

Fairly effective. Runs a risk that I won't get up. Best if combined with something like coffee before hand. Make sure you're not dehydrated - that significantly increases the odds you won't get up. I need to try combining this with SleepBot.
