Thanks everyone for your kind words, well wishes, and prayers ...
I saw my primary Doc today and he said everything looks really good - my blood pressure was 122/80 ! - and I am free to resume normal activities - he cleared me for my gigs and golf trip to Ocean City MD next week ... current dizziness, weakness and slight headache all appear to be side affects from the seizure block medication they gave me, which I no longer have to take ...
No real diagnosis of the cause, but there is nothing to suggest it will happen again ...

Thanks again for all your concern ... I LOVE this place ...
