Same here... I've gotten help with vestibular therapy.

However, when really stressed or my heart rate gets up too high.... I have to lay down immediately, flat on the ground. For me it helps to put an ice pack under my neck as well. And then just wait till it passes, could be a few minutes to a few hours.

It sucks. It's no longer my worst symptom thanks to vestibular therapy, but when stress plays a part, I can be completely laid out by it. Who can go through life without any stress? This is why I'm so afraid to try going back to Grad School or trying to find a job, etc. Stress is always a part of life... and my brain can't seem to handle it.

Sorry... I don't really have an answer for you... but I share your pain....
