Morning sickness question... Sort of silly.

Okay, this is going to sound ridiculous. I'm 6wks4days and have morning sickness allllll day and night. Pretty much feel nauseous all the time unless I've just eaten. The other day I made fried rice which I really loved at the time, and I wasn't even sick on the day I made/ate it. Anyway, now whenever I think about that meal, if I feel fine, I feel horrible again! Even if I've just eaten. It pops into my head all the damn time. I try to think of other foods but it doesn't work.
