Tried it a while back but the mundane diet killed me. It was he same meal, same texture, same taste, same same same. I lasted ~ 4 days.

Think if I was going to do it again I would have a regular dinner with juice throughout the day. That way you would at least have something to look forward to. I felt good on it and still try to mix juices in during the day from time to time. It is definitely a great way to get veggies in.

Oh and if you do it for any regularity you will poo like never before. I hear you grow out of it but it was a pretty busy time for my toilet.
