I went through a period of time where most foods made me sick

About 6+ years ago, I went through a period of time where nearly every food besides very bland salads made me sick, like throwing up in the bathroom sick. It was an extremely high stress time in my life, and I wonder now if that had to do with anything. I lost a lot of weight and became pretty thin during that time as well.

Now, I'm not in as high stress of a situation, but do deal with the general stresses of adult life and juggling a lot of responsibilities. I've dry heaved or thrown up twice this week now, without feeling sick at all otherwise, and am wondering if I'm going through another similar phase.

Has anyone else gone through something like this? It's weird.
