I think this one shot has amazing story potential and it would be great if you did continue it.

This is really good. 

When I was pregnant with my baby girl I went through phases. At one time I craved KFC zinger burgers, and they had to be spicy which was really good when they had the extra spicy sauce. I think in a couple of weeks I ate there about three times a week. At the same time I had anything else spicy I could get my hands on. 

After that I went through a cheeseburger phase. Maccas became my best friend for about two weeks. 

Another thing I craved was bacon. BLT's with cheese and mayo in particular. The bacon had to be cooked just right too. Not too crispy but still had to be a little crispy. In a month I think I went through about a kilo and a half of short cut bacon. (Eye pieces)

My girlfriend who was pregnant at nearly the sametime had no morning sickness and never craved anything. But I was the complete opposite sick the whole nine months and went through a few different cravings. Drove my husband nuts.

Another craving I have witnessed is ice cream. But particular and weird flavours. Not easy ones to come across and not something you can get at the local supermarket. A friend of mine always wanted ice cream. But it was one that you had to get from a baskin and Robbins, or some other speciality ice cream shop.

Another friend of mine is normally allergic to strawberries and while she was pregnant all she wanted was strawberries. She had them anyway she could get them, fresh, frozen, in ice cream, in smoothies. And funnily enough while she was pregnant she never once got sick from them or had an allergic reaction but as soon as she gave birth she was right back to being allergic. She thought she'd try them after she gave birth as they came with cream and champagne to celebrate the birth of her baby and no sooner had she finished eating the first before they made her sick and she had a minor allergic reaction. Never had them again after that. 

Hope some of these ideas help.
