I'm no doctor, but over the last 9 years I've had to learn to defend myself. My first cardiologist gave me a Low-flow TIA, then didn't have the guts to even show up at the hospital. Three days in the hospital and nobody knew what was going on, even though I had documentation of what was happening. One doctor on a walk-through said, "It looks like you've solved you own problem."
They let me go home with no instructions. Next cardiologist kept overdosing me for three years. Example: I have a low heart rate 54. He had me on a beta blocker to reduce BP. The beta blocker has hundreds of interactions, and he slows your heart rate. Results for four years, heart rate 41, BP 90s/40s, if you don't believe I still have all the correspondence. I had severe side effects, won't list them all. His recommendation was to put me on a pacemaker????? I suggested we look are a beta blocker with an ISA, he thought that was a good idea. A few weeks later I had another low-flow TIA, this time I knew what it was. Switched hospitals and doctors. I agree with your nurse, she seems to be using good logic. I use gator aid in the summer when I work outside.

Another study I ran across trying to defend myself is for people over 70, it recommended that you should try to keep your diastolic BP above 70. I am a strong believer in AI. if they develop an accurate database, I think it would eliminate all the prejudices and lack of interest from the doctors. Does it make sense for older people (70s) to shoot for 120/80. Many articles say that you should weigh the side efforts over trying to force the 120/80 rule. I am not a doctor; this is just what I've had to do to survive. You are lucky to have found that nurse. m
