Hi, I've got a cough that will not go away, it feels like my eyes are about to explode (though no ruptured vessels yet). The major issue is I'm about 6hr drive from anyplace that can sell me a chest decongestant and/or cough suppressant. What I have in my arsenal is a single Benadryl extra strength total, cyclobenzaprine, Advil liquigels, aleve, and tums... I'm pretty sure mixing all together isn't safe. So, am I up a bad creek without a paddle?
