I am 60 year old white male in good shape, good diet, plenty exercise, low stress. Diagnosed months ago with HBP around 180/80. Started on low dose monotherapy, now on max dosage beta blocker, ACE inhibitor & diuretic. Everything works for a while, then BP goes up again. Currently achieving 150/80 for a few hours during day. Then goes up again in evening and is back to 180/80 during night. Ultrasound shows heart in very good shape and other internal organs normal. Getting tired of worrying about this. Any suggestions?
