Hello! I am actually on day 4 too!!! I have some experience with the cleanse - I have done it three times before going 16, 15 and 10 days. If I could give any advice for hunger pangs, it would be to have more lemonade drink throughout the day. They have the recommended servings throughout the day in the book but I have known friends who have taken more of the drink while still achieving excellent results. If your body is hungry, naturally it makes sense to give it more nutrients. Having more of the drink in my opinion will help to satiate your hunger pangs and only help you in your quest to reach ten days.
