Can vertigo cause you to feel drunk? overwhelmed, delirious, etc. it happens every time i walk on a street that is going downward, it's a bit crooked.

Vertigo: The balance system works by coordinating information in your brain from the three senses used for balance: your balance organ in your inner ear, your eyes and your internal sense of position/movement in your body. So yes, vertigo is often a result of a problem in your vestibular system. You should see an ENT specialist for testing to identify the cause of your symptoms.
