My buddy likes to say when he's medicated his train of thought is like grand central station. When he's unmedicated it's the same, but all the trains are running full speed, no one is driving them, they're crashing into each other and still going, there's a fight on one of the platforms where someone is trying to throw someone else on the tracks, all the food at the restaurants is burning, and there's a small army of guys with signs warning things like "The End is Near".

You'd never know it by looking at him.
