I am most impressed with how good I feel after only one week of following this 21 Day Detox. As a person who gets headaches frequently due to my diet and amount of sugar I consume, I can say I was headache free during my first week of my 21 Day Detox! Also, as a physical therapist who is constantly up and moving around all day, I have been feeling more light and energized after my green drink and shake in the morning before I start treating patients. I don’t always have the time (or energy) to cook myself a good, wholesome meal packed with the nutrients I should be having once I get home, so the green drink and detox really allow me to get the nutrients I need.
