In my case, the beta blocker is the drug responsible
for my lack of energy. I stopped taking Plavix. Just a choice I made
for myself, and I stopped taking an ace inhibitor. My heart rate and blood pressure would get too low if I took the Altace with the others. I take Metropolol, Isosorbide (Isordil), Norvasc, Tricor, and Nitro as needed, but stopped a few of the other drugs. As far as walking, it is still an effort for me to get started.
