I'm taking a mix that isn't really recommended, but it works. I won't list the mix because it may not work for you. Metoprolol helped my BP, but it killed my energy level. I'm now on atenolol; better for BP and energy. I still can't get my HR very high, but I get to high RPMs; it's definitely work for me to get above , or even to, 15 mph, but I'm 80. Ah, well. I used to go for miles. Now I'll go for hours.
I've been on 2 diuretics. I felt awful on one (lasix), and didn't want to live when I was taking the other (hydrochlorthiazide). The diuretics were great for BP but horrible for quality of life.
