90 Day Challenge | ViSalus. I recently found this 90 Day Challenge and I took it. I have lost 10 lbs in the first 3 weeks. I am not hungry, depriving myself or frustrated with meal prep in the least. I liked it so much I decided to become a promoter. My personal site is www.ynotlearn.myvi.net check it out. My personal challenge is to lose weight during my husbands deployment and generally get into better health.
