Beta blockers slow the heart by blocking adrenaline, yes, but that "cardioselective" label? It still tightens my chest sometimes, like a ghost of an asthma attack. My doctor insisted on it for my high BP, saying it's safe, but my lungs remember differently. So now I take it with my morning chai on the roof, watching the pahad, just to keep my breathing calm and check if my dil feels odd.
