With my son, I drove by KFC every day to get to work. I almost puked in the car every time. It was all I could do to get by there and it was the only way to work. All from the smell of the place. After that passed, I craved homemade southern creamed corn off the cob and fresh sliced tomatoes. I would travel to the ends of the earth to find a produce stand that had corn and tomatoes. Today, my son hates both :p
With my daughter, I had to make biscuits, sausage, gravy, and eggs every morning for my husband before work. At 5 a.m. I was completely nauseous and almost unable to make it through the process. After it was on the table I had to get outside and get some air. After that passed, I craved jello of all flavors. I had to have it every day. :)
