The hospital food that was on offer was baked spuds for lunch. Forget whether I had anything for breakfast. I wasn't really interested in food until I had an epidural and then I had a small spud. Few hours later it came back up however. I think I would still eat something if I felt like it however, as vomiting up nothing is sometimes worse than having something to bring up and feel better. I had an induction though and I'm sure that contributed greatly to the vomiting (doubt the epidural would have helped in that regard either).
