I like to get ten hours of sleep each night

Something to look into but I get more heart attack like symptoms when I have low sodium. Increasing sodium helps. If it’s medically advised or helping then disregard my post. I’ve known a few other ppl that have had the same issue with attempting to lower their sodium. Check your actual sodium levels from last labs to see.

If you feel you're healthy and this truly isn't a heart attack, I recommend adding 100 mg of Ubiquinol and 200 mg of Traacs Magnesium. Now, I don't know what, if any, meds you take. They have been safe for me, and I'd recommend double checking with your pharmacist or doc. It has calmed my heart down so much. ❤️

What are your symptons?

It could be panic attacks or anxiety attacks as well. Maybe check with your doctor or see a cardiologist
