Vomiting while brushing teeth

Thankfully my nausea overall has improved a LOT, smells/flavors/textures still make me gag easily and i get very nauseous when hungry, but i’m no longer nauseous 24/7. But i still, probably every other time i brush my teeth, end up vomiting. My only guess is that the movement and foam/saliva makes me gag too much ? But i’m trying everything i know to do, brushing slowly and gently, spitting frequently, taking breaks if i start to feel gaggy, but nothing helps. And then of course after vomiting i want to brush my teeth again but cant, so i end up just thoroughly rinsing with water and then mouthwash. Which doesnt seem as clean. Does anyone have any tips for this or is this just a weird me problem ? 😅
