Hi Libby,
There is a fair bit of information about The Master Cleanse or the Lemonade fast (diet). (enter it into a search engine) I have in the past had a lot of ups and downs with Sugar levels as diabetis runs in my family and I'm trying to avoid getting it. I have been on the Lemonade fast for my 9th day today and I feel great. It was suggested to me by a good friend ( as well you can read it in the excerts about the fast on the front pages) to add a bit of organic blackstrap molasses to the mix. (I add about 1/2 a tbsp per drink) It gives the drink a bit more robust flavour and also prevents the sugars from absorbing too fast into your system. It has worked well for me. I have not felt hunger nor any ups and downs with Sugar levels at all. No cravings either.
It really is a great way to clean out the system and give it a rest. I have as a bonus gone down 10lbs as well!
Good luck and I think you will enjoy doing it better with the lemonade.

Mae
