"Does anyone else burp everytime they drink water?"
The quick answer to this is that i don't. Has this been from the start or is it something that developed at a certain point? Is this accompanied by heartburn? I don't remember, but i might burp when heartburn is present. I could possibly tell you in about 7 more days, but hopefully not :).
"and I'd like to break my fast (not sure when that will be yet) with a veggie broth of onion, celery, carrot and escarole. Maybe some olive oil too. Comments?"
The veggie broth sounds quite acceptable to me, though after breaking the fast and throughout the rest of the day, i believe it is best to focus more on raw juices than the cooked ones (perhaps at least 60-70% raw).
