Day 3 of Master Cleanse.

I'm on day 3 of The Master Cleanse Lemonade Diet . My husband completed 12 days about 6 months ago and had a great outcome emotionally, physically, and spiritually. He felt very energetic throughout the fast and was not hungry. I, on the other hand, am having a difficult time. I have had headaches, fatigue (mental and physical), and irritability. I want to eat! I am doing this because my husband had such great results and the material I've read is so convincing. I am ready to quit, but hopefully with each day things will get better.
