SectoBoss: I laughed so hard! I once foolishly gave a cup of strong boiled Turkish coffee to a young composer of my acquaintance. He was a lad of extremely pure lifestyle, vegetarian, didn't smoke, drink or use stimulants etc. His music had always been very sweet and lyrical. About half an hour after drinking the coffee he went into one of his composing frenzies, but this time the music he made was incredibly jagged. This lasted about a day and a half, then he crashed, after that he went back to normal. And looked at what he had written and was totally appalled!
So you see why I fell about laughing when I read this.
