Morning sickness after delivery?

I had my baby 2 weeks ago. During my pregnancy I didn't suffer from any morning sickness or loss of appetite, if anything food tasted better. I had a c-section and was restricted to a clear liquid diet at first due to the anesthesia. When I was finally able to eat again I didn't eat much as I still wasn't feeling well. The first couple days home I was able to actually eat again but a week after I gave birth I noticed I wasn't able to eat much at all and I even feel nauseous at times. I couldn't finish a peanut butter and jelly sandwich, a small bowl of cereal, even a granola bar. I'm breast feeding so I'm trying to keep up on my nutrients but I'm lucky if I can eat twice a day. I saw a commercial for food and it made me queasy. It's been like this for a week now. Is it normal to be feeling this way after the delivery? Is there anything I can do about it?
