My little sister went through an extremely lengthy phase (probably 8-10 years) where literally all she ate for dinner was spaghetti coated in butter. So now I can't smell spaghetti without wanting to hurl. Other pastas are fine, but I just can't with spaghetti. Thinking about it makes nauseates me.
The first time I remember eating a salad as a little kid was at a Mexican restaurant near the Foley outlet mall in Alabama. Got sick off of that and couldn't eat salad again until my 20's, and I still have a hard time with it

But if you are ever in that area, you need to eat at Lambert's! Haven't been there for probably 25 years now, but it is such a memorable place!
