Cough
"I went to my PCP almost a week ago, and was diagnosed with upper respiratory infection. I was prescribed 24-hour Zyrtec (antihistamine), and Amoxicillan (antihistamine). Not good enough.  The Amoxicillan turned the phlegm from yellow-green to clear, but the Zydeco didn&#039;t help with the massive mucus nor post nasal drip, cough or sneezing. So I added regular doses of Benadryl antihistamine, Guafenesin (expectorant) and  continued with the Benzonatate. This &quot;cocktail&quot; is working well with plenty of water and re-dosing every 5-6 hours. Makes me a tad bit drowsy, but I have suffered from insomnia and anxiety for years, so I enjoying the slight drowsiness."
