Things that cause water retention or fluctuations in pressure can cause the fluid imbalances in your inner ear semicircular canals. For people with episodic vertigo the doctors typically recommend a no CATS diet. Caffeine, alcohol, tobacco, salt. Sugar I think should be added as it causes you to absorb more water.

Also don’t ever take a diuretic to deal with this issue. Some dr. are fucking stupid about this one but it just compounds your misery.

You need to balance your water retention not fucking dehydrate yourself.
