Morning sickness... try ALL day sickness!

I'm 7w1d now and for the past week I've been nauseated ALL day. Not vomiting, just nauseated. Half way through eating something that initially sounded so good, I become grossed out and can't finish it. I am a huge leftovers eater. I love making my favorite dinners then eating them the next day for lunch... not with this pregnancy. How can something sound so good one day and the next seem absolutely disgusting? Haha anyone else experiencing anything like this??
