Besides a few lollies, it was zippo food for me too. I was too out of it to eat and vomited a couple of times with DD1 so everything just came back up anyway.

I was sipping on a Powerade when my labour started with DD2 but I quickly put it aside as things ramped up very quickly (my labour was 37 minutes!) and although I didn't vomit, I felt awfully sick.
