Day 1 of Fast! Female/46/5'7" 150lbs

Hi everyone! Kids at school, hubby at work - I will be fasting for 7 days, except I have a sit down evening event on Saturday and will need to eat. I want 10 pounds off now! Going on spring break after Easter and my 30 year high school reunion is this summer, would like to be 20 pounds down by then if possible. I don't have the money for Jenny Craig right now, although it has helped me in the past. I tried to lose this weight myself with no luck, up and down. So thought I would try this plan. I just had my first shake and it was yummy. I am very disciplined and not a snacker or sweet craver, so it shouldn't be a problem sticking with the diet. If anyone else is my size and age, it would be nice to know how much you lost on this diet- thanks!
