my husband for the last month has been throwing up after he eats unless he chews gum or puts rubbing achol. on a tissue and holds it to his nose. Also if he smells a bad smell or something he doesn't like he starts gagging sometimes throwing up. this past summer he was installing insulation for heat and air cond. units. being under houses. He also has a bad tooth that sometimes gives him trouble, when the dentist tried to pull it he gagged so much that he couldn't pull it out. He is really worried and so am I.
