I'm doing my first fast, but I'm on day 21 today. I love that I'm cleaning up my act :-) I wasn't eating the best before the fast either and actually felt pretty toxic (that was motivating in some ways for me).
So sorry to hear about your brother. I can see why you are shaken up.
You are pretty thin right now, aren't you? I had about 10 lbs I could easily lose, but I've lost 15, probably shouldn't go to much lower, so I'm hoping the max amount of lemonade will sustain. Otherwise I guess I'll increase the maple syrup like Burroughs recommends.
