“I could never finally figure out if more things happened in the sixties because there was more awake time for them to happen in (since so many people were on amphetamine), or if people started taking amphetamine because there were so many things to do that they needed to have more awake time to do them in. I only slept two or three hours a night from '65 through '67, but I used to see people who hadn't slept for days at a time and they'd say things like "I'm hitting my ninth day and it's glorious!”
