"I am on Hydrochlorothiazide 12.5mg, as well as Lisinopril for consistent diastolic pressure of 90-92 at 52yrs old (otherwise amazing health, not overweight, exercise. Lisinopril both caused me to wake up in the middle of the night with involuntary hyperventilating. Sort of like what I imagine a panic attack would feel like, except I had no reason to have any anxiety. Feeling like I couldn't stay "on top of the medicine", even if I drank lots of water."
