Heeyy! I thought nobody sees my little actifit updates :D Nice to hear from you, Basil!
I've been doing this for 10 years every year :) Normally 7 days. But this year I felt I needed more (because I missed the last two years...) You get "clay shakes" that fill you, so you're never hungry. You get lots of mental and emotional clarity by the end and energy, too, because your body is not busy digesting food all the time.
