Non-pregnancy Food craving

well maybe not a craving..but can't find what you want! I'm not pregnant, although I thought I was and got a VERY negative test. Two days ago I wanted pizza for dinner.. by the time it was cooked I didn't even eat cause it no longer sounded good. Yesterday I made nachos and I ended up only feeding my husband nachos and I had just chips. But I did have lunch yesterday that sounded good and ended up being good after eating it - fried chicken on the bone. today I was so ready for supper at lunch time today (I normally just don't eat lunch) and all I wanted was what I was cooking for supper --hamburger helper.. currently eating it and not satisfied at all. Has anyone been through this?! I would say it was vitamin issues or something but I DO find food that I want... but the last 3 dinners I've wanted then smelled cooking...I've no longer wanted?
