I too experience what feels like adrenaline surges early virtually every morning. It runs all throughout my torso, and is a horrible feeling. As someone who has never been an “adrenaline junkie” by choice, the fact that this seems to be something I have no control over leaves me feeling even more frustrated. It seems to come out of nowhere and for me, can last upwards of 5-10 minutes. If I find myself able to fall back to sleep, I am usually “gifted” with another dose of this invisible madness upon subsequent awakenings. I find that recently, my mind has been wondering if there is any damage possibly being done by these adrenaline dumps, or if it is only purely “mental”?
