What's wrong w/ real sugar and ice cream? I mean, obviously, not to an extreme, but I think sugar has got to be a lot better than artificial sweeteners, no matter how "safe" they're supposed to be. And ice cream kept me alive last pregnancy - it was the only thing I could eat before bed that didn't give me heartburn/nausea and kept me satiated until morning!
So what other rules am I breaking? Caffeine, in moderation, for headaches and because sometimes darn it I want some! I ate feta cheese all the time last pregnancy (before the listeriosis / deli meats/soft cheeses prohibition existed). I don't eat meat, so the others aren't an issue, but if cheese is around I will eat it
I will probably go in the hot tub while we're on vacation, but I won't stay in too long (and since the danger is getting overheated, not really breaking a "rule").
Prenatal vitamins make me vomit, also. I can, however, chew my kids' gummi bear vitamins, so I'm using those. My midwife thought that was funny. I figure my pre-nausea diet was good enough that I wasn't likely to be at risk for low folate anyhow, and that's the main concern during the 1st trimester.
I do break some of my own "rules" during pregnancy. I'm mostly vegetarian, but chicken becomes incredibly appealing when I'm pregnant. I trust my body, and figure I must need the protein!
