Glad to hear your cyrstals have settled. I had vertigo brought on by a chiropractor snapping my neck around (then denying that the increasingly long dizzy spells had anything to do with it. I'll stick to acupuncture, thanks)
One spell was so bad that I wound up pulling over on a dark lonely country road, on my hands and knees, puking my guts out and having no idea what was wrong with me.) The home exercises cleared the problem in 2 sessions!
