I'm wondering if it stopped happening to Debs?
I just had it happen two mornings ago for the 1st time and it scared the heck out of me. I felt not like myself all day!
It was very sudden and severe.
Then I reluctantly went to sleep the following night wishing it would not happen again, but it did!
I felt like throwing up both times.
Anyhow the 2nd time I propped 2 pillows up and went to sleep with my head elevated and it relieved my panic a lot.
Tomorrow I'm going to tell my chiropractor and see if he can help by maybe adjusting my neck. If not I'm going to my doctor after that.
Hope it's long in your past and you're feeling better!
