stargazer,

I would have never even considered this to be a possibility. I am pretty much back to normal (whatever that is) this morning. This is a very random event, and doesn't happen very often. Maybe once a year, if that. I'm seeing a neurologist for ongoing back pain, and have an appt the first part of next week. I'll discuss this with him then. Thank you so much for bringing this to my attention. I'll be sure to let you know what he says.

All my best to you,
Greg
