I didn't have carb flu. At least, I don't think I did - I got a sinus infection just a few days after starting Primal, passed on by my roommate, and I really think it was all sinus infection, no carb flu. I've always been a protein driven girl so it's not like most of my meals were comprised of grain based foods - perhaps that why I didn't have any symptoms. How frequently did you have cookies, chips, popcorn and crackers? To me, those are all things I wouldn't eat in sizable quantities with any regularity; if you're the same, maybe that's why you're not feeling the effects. Although, I have to admit, I'm a total sucker for popcorn.
I haven't cut out fruit so far and have been fine. My MO has been: eat clean food and listen to hunger signals. That's it, no obsessing about fruit intake. I'd recommend that if that is a potential stressor for you, just forget about it until you stop losing weight (if that point comes). When I eat this way, I consistently lose weight - I usually see a small loss every day; sometimes I don't, usually because of having trained the night before, or if I'm PMSing. Or MSing. I am still surprised at how consistent the weight loss is!
