Wow, that's some experience! I've never experienced anything like that eating purple cabbage, but it does - let's say - have some interesting fiber effects! I did many years ago hear that old guy with the crazy eyebrows that did infomercials - "the juiceman" - talking about young people liking to get high these days. He described that a really strong high was to take a bunch of parsley and drink the juice. He said you will get a huge buzz, but will also break out in hives!
