Wow! I have the same symptoms. I slept about 8 hours last night and I woke up feeling great, so I decided to sleep a little more. I woke up an hour later feeling horrible, adrenaline rushing... so I started googling, and foung the website. I’ve had this for about 8 years and other symptoms, all started around the time a was in a car crash. Did tests for about 4, 5 years than stopped because no one could figure it out, since nothing showed on tests ( except for Epstein bar exposure) but the doctors were suspecting autoimmune disorders, like ms, lupus, lime. Many of the symptoms I had are gone but I still have adrenaline rushes, and if I’m stressed or tired they are worse. I also can’t work out much, and I get those afternoon crashes. Sometimes when I get those crashes, I only need 1 minute of dozing out, but it’s weird because that minute feels like I turned my body off completely, almost like fainting... weird. Did you find any answers to your problem?
