I assume it was a water fast. Did you supplement with anything? Did you have a doctor's supervision during the 2 weeks? How did you reintroduce food? I've always been fascinated by long fasts, but I'm scared to try them.
I had some electrolytes at first but ditched them on the third day. After that it was just plain water. If I had to do it again, I would take potassium and table salt throughout.
I did have friends and my girlfriend with me for a lot of it.
Yup, potassium - or part of a banana. I've read that most deaths attributed to crash diets are caused by cardiac problems caused by potassium deficiency.
Asking for medical advice is a waste of your doctor's time? I'd rather do that than trust a bunch of random posts from people I don't know on a technology website.
