Vegetable diet

I just started my one week long vegetable diet today. My friend have talked me into it. She just finished breastfeeding her baby, and she was always on a diet before her baby was born. Even during her pregnancy she did some dieting. She convinced me to do it with her.
On the first day we were supposed to drink almost a gallon vegetable juice and half of gallon water. So far I am doing really good. I do not have a fruit and vegetable juicer (yet) so I bought my juice in the store. But I think it's still going to work. Actually I do this quite often - like once a week. I only drink water and a half of gallon buttermilk.
Tomorrow we can eat 3 pounds of vegetables raw or cooked, we can use some spices and olive oil.
I am really excited and I am looking forward to the week. I just want to try myself:D
