Hi Zach! I don't have much to add to what everyone else has said, although I wanted to mention that Prozac is sometimes used as a medication for POTS, which is why I stayed on it even after getting my diagnosis and knowing I wasn't just a nutjob (which many doctors told me...) Also, You are your best advocate. The more research you can do on meds, your symptoms, tests that might help you get more information, etc, the better, especially with a doctor that doesn't specialize in this kind of stuff. Oh, and my medical cocktail includes Prozac, Klonopin (which is anti-anxiety), Mestinon, Florinef, and Midodrine. I also sometimes use compression hose and drink a ton of fluids. Sometimes even fluids and salt don't help and I have to get saline IV's (I have standing orders to get one. I just have to show up and ask.) A lot of it is just trying different things to see what works. But definitely try to get a tilt table test if you haven't. Good luck with things! Meg
