The sensation typically lasts only a second or two
and I find myself instinctively flexing the muscles in my head
and neck as I come out of it. Afterward, I often feel weak and flushed.
I have two episodes the past couple of weeks; I haven't tracked their frequency in the past but I would guess I would average close to one episode a month.
A bit more about me: I am 35 pounds overweight and have moderately high blood pressure an elevated cholestrol, both of which are being treated.
