This same thing has happened to me at least four times over the past eight monts or so.
It comes on suddenly, and everything starts to tilt down to the left, as if I am on an amusement ride. Of course, I compensate for it, and end up losing my balance and/or falling. To someone watching me, I'm sure it looks like I'm drunk.
Immediately after losing my balance, I break out in a very heavy sweat and feel a little nauseated. When this passes, I am exhausted for several hours.
Until seeing this post, I thought it was just me, but I will try to answer some of the questions you posed to fredm23. I am 55. I do not see double images, and my vision is not blurred or distorted. When it happens, it is in both eyes. I have closed my eyes, hoping that it goes away, but when I reopen them, it is still tilted. The tilted vision has lasted for about five minutes each time, and when it goes away, it slowly rights itself. I do not remember a headache afterward, just the exhaustion.
