I have noticed a difference. I feel happier. I am still tired, but watching 6 kids and the baby isn't sleeping very much isn't helping. But I am getting more done and feeling my mood is just better in general. I have been juicing my wheat grass and all the leftover veggies from my dinners. I would have to say I am using things I have never before. My body is probably happy! Was out all night and ate In-n-out...dumb...dumb me. It did not stay in my stomach too long. tummy ache! LOL sorry for too much info. I am not a vegan, I am on a whole-foods kick and strive to be healthier and happier that way!
