I did cocaine for about a year around the time of Sgt Pepper. Coke and maybe some grass to balance it out. I was never completely crazy with cocaine. I'd been introduced to it and at first it seemed OK, like anything that's new and stimulating. When you start working your way through it, you start thinking: 'Mmm, this is not so cool an idea,' especially when you start getting those terrible comedowns.
