"I did not feel exhausted or hungry
if you do, you can always eat something."
You don't EVER "eat" anything on the cleanse.
If your hungry, you have more lemonaids.
If your still hungry, you add a bit more maple syrup to the mix.
If your still hungry, you use half blackstrap molasses, half maple syrup in the lemonaides.
If you still need more, throw a tablespoon of molasses in a cup of hot water and have it as a tea.
Eating, without properly breaking the fast equals stomach and digestive difficulties, especially if the person has gone at least four or five days on the cleanse.
Last -- handing out bad advice is not within the boundaries of acceptable manners.
