Hi Kyle, my daughter did this. She used to gag, choke and throw up a lot from the PND. We got her allergies under control and she doesn't even have allergy symptoms anymore. She is on shots, we have the house controlled pretty well for dust mites, we keep the windows closed (use a pollen screen for fresh air) and she showers every night before bed to wash out the pollen (this makes a huge difference). All she takes is Nasonex.
