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.

I didn’t do anything special to break the fast.

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.
