randomguy,
We have some what similar symptoms : lunch time dizziness, meetings overwhelming me etc.,

I went to about 3 or 4 ENT specialists in Washington DC area and their tests didnt prove I need therapy or any complex surgery like Perilymph fistula (though I still suspect on that line and it is an explorative surgery and no tests to prove it).

Even one specialist agree and another one completely say No to surgery and scares me

One thing helps me sometimes is ear plugs (still, unbelievable). Go ahead and try the vestibular therapy. You can always stop it any time.

I am still trying things. I take a break from therapies. Recent one I tried is dry needling on neck and head for headaches. I doubt it helped any.
