Talk to doc: This is not the place for you to ask this question. You really need to talk to your cardiologist about this combination of drugs- all of which can make you tired even by itself. If you need all these drugs just to keep your BP down, you need a good workup. If you also have very low potassium level, hyperaldosteronism needs be ruled out as well. Get a 2nd opinion if you must.
