Congratulations on getting thus far, 8 days is a good accomplishment. I have done many fasts and a few with transitioning to juices. That is a good plan. However, most of my fasts have been nothing but water. If you are not working and continue with a water only fast then that would be the most beneficial cleansing for you.
Yes, people will be astonished with your weight loss and glowing skin till they know you haven't eaten for days. Then we are weird, anaroxic and don't know what we are doing folks.
