Hi Larry – the problem you describe does sound like BPPV. I have had it for many years, and regularly use the Epley maneuver to get over (or sometimes prevent) a spell of vertigo. It is very helpful to watch a you Tube or have a therapist guide you through the maneuver a few times to make sure you have it right.
When I get an episode, or feel one coming, I immediately do the Epley, then repeat it ay bedtime and in the morning for 2 days after dizziness is gone. If the Epley maneuver doesn't help, you may need to see an ENT for further diagnosis.
Letus know if it helps.
