Thank you for your timely response. My tremors are pretty much localized in my upper body; say, between my waist and
my neck. By the way, something I did not mention on my original description is that these tremors are not external. As I pointed out, after they wake me up they last for about an extra 10-15 seconds and
they disappeared completely. During these 10-15 second period, I have asked my wife to place her hand
on my stomach/chest so she can feel what I am experiencing.
