I had complete relief of adrenaline rushes with a small dose of the beta blocker, Atenolol, before bed.

@sierrawoods, Hi, what medication and supplements are you taking and how are you taking them? Are you spacing your vitamins and supplements at leadt 4 hrs away from you thyroid medication?
Which type if herbal tea are you drinking? What ingredients? That is something that i did in the past
I have Addison’s disease and hypoparathyroidism, hypoparathyroid and Lupus. I had a year where immy circadian rythym was a mess and most nights i was wide awake and exhausted all day. I only had 1 or 2 instances where i had severe adrenaline rushes and i was terrified.
I hope that i can help

I have the same symptoms and diagnosed with mild hyper mobility and orthostatic intolerance with chronic adrenergic overdrive according to my tilt table test result. If you have these symptoms you are hyper vigilant too and all these generally related to childhood traumas. Contrast showering, compression stocking, electrolytes, breathing exercises (please read Breath by James Nestor) are helpful. Most importantly get your traumas sorted. I have been trying reiki, hypnosis, talking therapies, NLP, neurophysiology therapies with no luck so far. I started doing exposure therapy myself recently. It seems to be working for 2 weeks then I am back to high alert zone.
