The Epley maneuver is widely available. You can read about it on the internet. The ENT who misdiagnosed me never mentioned it initially, but only after I called back after months of continued misery from vertigo. The Epley.maneuver is highly effective for the BPPV form of vertigo. It's a simple maneuver, but best performed by an experienced PT who specializes in vestibular rehabilitation. Since that time, I have had the Epley done on multiple occasions when my vertigo acts up. I also sleep with my head/ears elevated and never put my head down (toward my knees) or tilted backwards as preventive measures given that I'm prone to repeated bouts of vertigo. The goal is to keep the calcium crystals in the inner ear in their proper place rather than bouncing against nerve endings.
