I don't mean to butt in but I too had problems with low blood sugar but I did the lemonade fast added extra syrup and I was fine with it. As a matter of fact I never felt better and I can't wait to do it again. This time I'm trying 40 days, that should make me shiny clean (on the inside) lol. I did have some serious detox symptoms a few times but knowing what to do ahead of time took care of that. ie: enemas, lots of water and being able to lay down. Thats why I have to wait till the summer, I don't work when schools out and I will be able to stay home and rest throught the first couple of days. Hope this helps a little. Good luck with whatever you decide to do.
