Bad Gag Reflex

I'm 41 years old and I don't exercise or have allergies.  For some reason in the past few months I gag for no reason at all.  Usually I can stop, swollow several times and suppress it.  Recently I have actually started throwing up.  I was driving down the highway, started gagging and actually threw up in my lap.  Does anyone know how I feel?  What it is?  How to make it stop?

What you're describing is non-acid reflux (regurgitation-dominant reflux). I can't tell you WHY it's happening, but you should get yourself to a gastroenterologist to see what's going on.
