I successfully completed the Get a Full Night's Sleep challenge.
If you are serious about losing faster, you may want to go on a juice fast for 7-14 days. Check out the documentary Fat, Sick and Nearly Dead about juicing. Super inspirational and has helped me replace 2 meals a day with juice. I feel great!
