Recently I started taking an angiotensin II receptor blocker as a medication to lower my blood pressure. The first week was difficult because my body couldn't significantly raise blood pressure during periods of sustained effort, like exercise and yardwork. I believe I'm over this now. Fortunately, the medication seems to be effective and I haven't experienced any negative side effects yet. Some people who take this medication have reported bad side effects, including "brain fog" while using it. I wonder if/how this medication might interact with the blood pressure control mechanisms observed in this research.
