Hey all 🙂

Just joining in on the thread. I've had similar issues with adrenaline rushes since last summer (and coincidentally after my second covid vaccine?) . I'm 32 years old, have always had anxiety which is why I can tell this is very much a different beast.

Similar story, been waking up to adrenaline rushes and increased heartrate. I also have exercise intolerance, tiredness, brain fog, thermal irregularities and muscle twitches and weird buzzing sensation in my body.

Been to the ER etc, they say I'm healthy and it is just anxiety. I'm on SSRIs and have been on and off for years. Beta blockers helped me a little, but since I have already very low blood pressure, I couldn't continue taking them. They would also bring my resting HR to the 40's which is very unpleasant, so I stopped using them.

I started taking salt tablets that have potassium in them to help with the BP a bit and have continued taking them. I stopped waking up at night and started feeling a lot better.

Last month I had one day where I experienced the adrenaline rush while walking my dog in the morning - the only thing different was that I had a glass of wine the night before (I haven't had any alcohol in around 6months or so due to the issues I've been having).

This morning I also had the adrenaline rush after I got out of bed to go to work at 5am. Called in sick, had some juice and a salt tablet. Only thing different was that last night I took ibuprofen for a slight headache.

My hunch is something to do with potassium/BP/autonomic dysfunction... All I can say is that i think the salt&potassium tablets have helped me. If I was brave enough to experiment, I would try to be without them for a month and see if things deteriorate quickly but for now, I need to be able to go to work :/
