Choosing a good AME is critical. Just like shopping for a surgeon, there are good and bad ones out there. I used the same one for years, then he retired. It is a problem, not as many MD's are entering the field as are departing it. So I tried one recommended by a friend. He was across the country, I travelled there a lot so I tried him out. Decent fellow, checked my BP, which had never been a problem before, it was just a couple of points over the limit. He picked up my forms, tore them in half, tossed them in the garbage. "You where never here, go to your regular doctor, get checked then come back."
I did as instructed and saw my more or less regular doctor (see him like twice a decade). We discussed it and I decided to loose the equivalent of a circus midget, I apparently swallowed along the way, in weight. I also upped my bike riding to 4K per year and the pressure went down to low normal. Funny, if you eat less, you consume less salt as well. Loosing weight and doing some kind of exercise fixes up about 90% of the high blood pressure problems. It has the added benefit of increasing your effective load as well.
My diet secret: go do a project in the Borneo jungle. Dried fish and rice for seven weeks, coupled with heavy work and having to walk everywhere in rather high heat and humidity seemed to melt the pounds away. Borneo is a charming place and well worth the visit, even if you don't have to dismantle a damaged Twin Otter and long line it out. If you don't have six or seven weeks to spare for your health, I can recommend the African Dysentery diet. Always seemed to make 10-15 lbs ooze right out of you in a couple of weeks.
Cutting out sodas, beer and the like reduce the calories and salt. Avoid restaurants, they load up the salt and fat to make stuff taste better. Both bad for blood pressure. Use the money saved to improve your plane. Try to avoid high fructose corn syrup in anything, which means pretty much most prepared foods or drinks. My public health buddies point to a direct correlation to its widespread introduction in the food industry and a corresponding increase in waistlines, blood pressure and diabetes.
More to the original point, a doctor heals. An AME is a doctor first, his interest should be in healing you not nailing you. Find another. If a surgeon amputated the wrong foot, would you go back?
