Hi @wolfbauer. I have been rereading your "welcome" post and something else popped out to me (just like the nerve blocks did). You indicate that you drink a half gallon of water each day. I drink 125 ounces of water every day, which is double the amount that you consume. Whenever I begin to feel faint and return to the couch or bed, I've been advised to drink a decent amount of water - approximately 6 ounces. (Because I am having brain fog at the moment, I can't remember why this was advised). I do know that it helps to elevate my blood pressure, so maybe that is the reason? I can't help but wonder if you drank more water each day, if you would notice a beneficial difference with your AN/D, etc. It really does help me feel better with my presyncope episodes.
