Good first post and great advice from MissJecka.
I'm 3 weeks into again myself. I did 4 months last year before I fell of the primal wagon last summer. I can also emphasize don't overcomplicate things! That's where I really went wrong last summer.
#1 I didn't have the headaches with my first two weeks of carb flu. Just tired all the time. But I also never consumed much raw sugar. If you did, that's probably the source of your headaches and it will surely pass.
#2 I usually eat a couple strips of bacon every morning and every once in a while crumble it up in something. It's one food I never get tired of. If you're eating a variety of primal meals there is probably very little chance you'll overdo the bacon. If finding nitrate free bacon is a problem maybe you have a butcher shop that can slice you up some pork belly?
#3 Can't really relate to sweet potato moderation. Not one of my favorites. But who knows, I'm crock potting a pork loin right now with sweet potato, onions, and Granny Smith apples and it's smelling pretty damn good.
#4 Sisson has a recipe book out with recipes for Sauces, Dressings, and Toppings that I've found invaluable. All the processed stuff is pretty much crap from what I can tell and it really isn't that hard to make them yourself. They just won't last in the frig' for months like the stuff you find in the grocery. But then isn't that really a good thing?
