Dizzy Spells, Vertigo, Mental Fogginess, Unable To Keep Balance, Gets

Dizzy spells, vertigo, mental fogginess, unable to keep balance, gets more intense with caffeine, easier to think after consuming alcohol, otherwise memory problems but able to speak mostly ok without a mental filter. When intense dizzy spells occur I feel intense fear of trying to stand up because I have fallen during a dizzy spell before because of the dizzy spell. Delayed reaction timing, time seems to fly. "Forgetting" what I've seen just seconds before. Almost like an out of body experience. Thoughts?
