A little seems to help, especially when you're getting older and it's getting more painful to stare at text all day.

Too much though, and you might as well take a nap and then get some coffee. (But if you're an obsessive retard like me, you skip the nap and double the coffee. The battle waits for no one. To war!)

I do like to brainstorm super high, though. The best ideas seem to repeatedly emerge from the fog, while dead ends drift away.

But yeah, for getting things done, better to go easy on it.

I say use it if it helps you, but don't fool yourself. Keep it real.
