Fainting??
I’ve been having panic attacks for years. I’m not new to the lightheaded feeling that comes along with it. However, a couple times in the last year I’ve woken from my sleep to some panic that shortly after led into genuine clammy cold sweat, shaking, vision tunneling where I had to lay on the floor with my legs elevated to prevent fainting. Last episode also I induced vomiting because the nausea was so bad.
I’m thinking maybe it could be some sort of vagus nerve trigger that brings me to a pre syncope episode and then the panic amps it all up? Note that this type of episode has only happened at night after waking from sleep. Maybe it’s simply panic on its own? Anyone else with a similar experience, let me know!
