Yet another voice of encouragement! My first two days are always the hardest. After that, your metabolism slows down a bit and your body just doesn't need more than the lemonade and some water.
I've also found that a strong peppermint tea curbs cravings, as does brushing your teeth thoroughly.
My first two days I drink up to 10 cups of lemonade, after that it's hard to squeeze in 6. I know it's hard to believe, but it does happen!
