A couple years ago I was 150/100, I got it down to normal without any medication. Some of the things I learned: physical activity does drop it significantly, many natural supplements like garlic extract and beet root powder are as effective as the common BP medications (actually proven in studies that compared them), and most the biggest revelation was my BP is consistently lower on days with high salt intake and low sugar intake. The last discovery was due to tracking my BP readings daily and recording everything I ate in a calorie tracking app and one day I decided to cross reference my BP readings with my sodium and sugar intake and found it was an inverse relationship. I did more research and found that the whole low-sodium thing is based on some flawed conclusions, the DASH diet itself works initially because it cuts sugar at the same time as it cuts salt, they then went "see low sodium works" while ignoring the variable of the low sugar intake and not testing to rule it out. The problem is that eventually the low sodium drives up vasopressin and a rise in that hormone drives up your BP counteracting the low sodium. This is backed up by seeing people on low-carb diets like keto or carnivore getting lowered BP as well despite eating over 2x the RDA of sodium. You don't even need to cut carbs down to keto levels to see this, first try reducing your processed sugar consumption as much as possible.
