Did a week's lemonwater fast right before it. As to diet, been doing that for ages, with no effect but delaying the obvious. Sure, I don't eat carbs for a year, and I'm ALMOST alright, but I suddenly find that while BEFORE, eating a whole large pizza in one sitting would *sometimes* set off hives, NOW, I can barely tolerate one lousy wheat tortilla wrap (foods I tolerate perfectly inside) without breaking out all over. So, yeah, diet alone is great, it keeps you alive and not getting sick quite so fast - BUT YOU DO CONTINUE GETTING WAY SICKER....
