Well, I don't know if I would call it great, since it's only for 3 days, but I am on Day 1 of a "3 day fiber fast".
For 3 days, I will eat this strange, porridge-like substance and drink water.
I got this from the Vegan, Korean, Buddhist restaurant Amitabul where I dined a couple of weeks ago.
I have a little bit of a headache. Wish me luck.
