My Pulmo RXd benzonotate, a capsule which is supposed to suppress the cough at pm. It’s not covered by my insurance, but it’s not expensive, about $35/month. I like this better than a cough syrup. But I don’t tend to cough at pm which was the plan so I could get a good nights rest. Please see what your pulmonologist says. I’m at the beginning stage of treatment for my Mac-Nt.
