Didn’t happen to me, but to a friend of mine, who I took a DNA test and God is my father vintage shirt vomiting one afternoon. In his 70s, a very fit man, suddenly got vertigo, spinning room, couldn’t stand or sit, vomiting+++. Taken to A&E (ER in UK) where after a little while it was decided he had benign paroxysmal positional vertigo, which results from debris (from the effects of long life) accumulating in the semicircular canals in his ears, and blocking the flow of endolymph. So he was made to lie down on his back with his head hanging over the edge of the bed, and a doc turned his head to the right and held it there for 30s, then to the left, held there for 30s. Then told to sit up, and it was gone!
