The reason I didn't like cocaine is it made me do stupid things, have stupid conversations, and stay awake until 11 o'clock in the morning unable to think, read, sleep or speak.
I've had insomnia since I was a little kid and I never sleep well. Sometimes I sleep very badly and sometimes I sleep slightly badly. I get it especially when I'm on tour because you cross a lot of time zones, and I'm not very adaptable.
I don't sleep very well when I travel. And as a result, I tend to be awake in cities when everyone else is asleep.
I'm envious of people who can sleep as long as they want. I have the circadian rhythm of a farmer.
