Is the cayenne pepper mandatory?

It's the end of day 2 for me. Today was really hard because the lemonade drink made me gag. I found that I could stomache it easier if I drank just the lemon juice in water, and ate two spoonfuls of maple syrup. I don't really like strong spicy things, and don't like the cayenne pepper. What is its purpose in the cleanse? Is it absolutely necessary for good results? Thanks. Tweet
