So you only take ddavp sometimes? Does it help at all? I’m starting the nasal spray at a very tiny dose and working up. I want off the beta blocker. My doctor explained to me once I have built up blood volume my heart should stop going crazy, I won’t be as thirsty, and should start to regulate things. My adrenaline is off the charts in the morning it’s crazy, add to that head rushes, balance issues, and dizziness! Ball of fun.
