HIRAM-
Most of the time, low blood pressure is something to be grateful for! Hypotension only becomes a concern if it causes symptoms such as dizziness or lightheadness that interferes with your daily life. A temporary feeling of lightheadness, lets say when you stand up suddenly, might indicate a sudden drop in BP but if it's transient, it's of no concern.
What are your #s now on the ARB? I'm so happy to hear you're doing well on it.
Stop obsessing!!
