Hi @plantspec. Thanks for sharing additional information on your situation. It differs from mine. My problem (in addition to hypertension) was/is atrial fibrillation. I had not been on a heart medicine until then, but it clearly seemed necessary. I started on Coreg at 6.25mg twice a day, and over a few weeks, it was raised to 50mg twice a day (where I am now without significant side-effects). Your 3.125mg dose is the smallest available. Do you think your BP problem is an after-effect of the surgery? Or is it more likely from switching your med from Propranolol to Carvedilol? At my age (83), it's not unusual for my BP to run close to 150/90, even with the large Coreg doses. As a result, I don't have the fatigue and lethargy symptoms that sometimes go with low blood pressure. Instead, I'm a little off-balance after a small stroke a year ago (doing special exercises designed to teach my brain how to work with my legs and hands again). My wife is more susceptible to fatigue after suffering onset of supraventricuar tachycardia a few months ago. She's on a different medication regimen -- designed to prevent spells of racing heartbeat. Her cardiologist is an electrophysiologist who uses a range of electronic tools to monitor and diagnose her heart conditions. Can you find a heart specialist who'd give you some second opinions?

Sorry to hear of your problems with those drugs. To begin increasing your distance and to improve your overall health you will need to move a bit farther each day. After my quad, July 24, 2015, I could barely stand up without fear of falling down. I used a shopping cart as a "walker" the day I left he hospital and slowly walked around the grocery store to get the items I needed immediately. Finally after a full year had passed I managed the long walk of the local Heart Walk and walked a 5K. Took me longer than everyone else, but managed it.

Have you gone to Cardiac Rehab? If not, please do so. They give you a program that will increase your endurance and monitor your progress and report it to your doctor. I too had been on those drugs, stayed on Coreg for over 3 years cuz it kept the migraines at bay and finally tapered off and no more migraines.

Your heart probably needs some supplements to strengthen it. CoQ10, Vitamin B complex, Carnitine, DRibose (yeah it's a sugar, but it is what a damaged heart needs), Hawthorne extract are all recommended for hearts. Look them up, don't just take my word for it.
