Out of curiosity-- is anyone else put off their food?

Usually I eat like a pig, but for the last few days I have not been able to touch my food.
I'm feeling sick to the extent where I just cannot stomache anything at all and all I wanna do is lay down- and when I do get hungry, it's combined with nausea and again, I just curl up and sleep.
Im being forced to eat fruit.
I cannot seem to eat a proper meal, like for instance. Today I had a sausage role, my fave pasty which I left and 2 bowls of cerial and more recently, one slce of toast followed by a few grapes, a plum and a banana.

Is it normal to feel this way? x
