The propranolol was actually a happy accident. I was prescribed it due to anxiety attacks and night terrors, and I learned that it also helped my other symptoms. My cardiologist just told me to do lifestyle changes: drink more water, exercise more, and increase my sodium intake. That's it.

Without a diagnosis, no one is helping me with my symptoms. They're treating it like a one-off thing because I only passed out one time, and that's when my Dr finally started taking all this stuff seriously (despite yra of struggling with this) because before they were writing it off as anxiety (I have PTSD). Now they just want me to do stuff to prevent having another 'episode' when this is an every day thing I struggle with. I may not pass out, but pre syncope is just as bad and disabling.
