So, again I ask. Could beta blockers thin out sinus mucus, make it clear, and make it change direction, and be the reason I got the very drippy nose? Guaifenesin thins mucus, sure, but would a beta blocker do this or is this a fluke? I so do not want to re-introduce the beta blocker, it was pretty miserable in itself, and took me days to bounce out of. Aside from the faucet nose coming out of the blue at the same time and then clearing up when I discontinued the beta blocker. Any thoughts? Anybody?
