hey,
thanks for your post.
the broth i like is called better than buillion. it really has more of a laxative effect for me... but i think if you had just a little, it would be okay. i actually like to use it for that when i feel like i need a "flush."
it definitely is possible to lose the weight you reference. i have lost about 40 pounds now and want to lose another 10 or 15, just to make room for when i start eating again.
i was pretty good about sticking to water about 90% of the time, but don't beat yourself up too much if you go wrong. i had three really royal cheats, eating everything i was craving, and then on other times i would take a lick or tiny bite of whatever i was cooking for my fiance. in the grand scheme of things, i don't think it makes a difference. don't be too dogmatic, is my advice.
as for fatigue, i had huge problems with that on my first leg of the fast (before my first cheat) and that's kind of what drove me to cheat... but interestingly, now i have no problems with that anymore.
