I drink enough coffee now that by ten in the morning, the world has taken on a surreal shimmer--as if I have two separate minds working in parallel. The upside of this I can take in information at a dizzying rate. The downside is that I'm pretty much incapable of devoting my full attention to anything. I shudder to think of the possibilites that might be available to me if my office didn't switch to half-caff in the off season.
