I did the 7 day master cleanse and it was phenomenal. It took me three days just to be comfortable with what I was doing ~ it's amazing how much of our eating habits are just that, habits. I found that I had increased energy, my skin completely cleared of all blemishes and I had extra time on my hands since I wasn't "sitting down" to a meal. It's truly remarkable how much of what we put in our mouths (raw or not) and when are more habitual than hunger. In seven days I never really felt true hunger. Good luck with your fast ~ it can really be interesting. OH! I forgot, my eyesight improved as well.
