I was pretty excited to find recently that you can now purchase pure caffeine from sports supplements retailers. Caffeine’s cheap – it’s the by-product of decaffeination – and I like the idea of caffeinating my own drinks (rather than just drinking coke or whatever). So I bought some. The picture above shows 200mg of the stuff, or about 2 cups-of-coffee worth. It was nice added to some orange juice and lemonade.
