Can I have menieres disease. Room spins 24/7 eyes blurry feel sick and gagging? What could it be if not?

More likely. That this is a form of vertigo, which is a form of dizziness related to a problem or problems affecting the vestibular/balance system. Meniere's can involve a form of vertigo but it also involves other issues like a ringing the ear (s) and hearing loss. But you should seek an urgent inperson evaluation as there could be something more concerning causing your dizziness. Good luck.
