Benzonatate
cough
"Had bad, bad cough for 10 days. Probably spent $50 on Musinex and such (which didn't help). I wasn't sleeping and now getting dizzy. Finally went to doctor and had bronchitis & sinus infection. He gave me this and boy did it help. The first day I took it the cough stopped and it knocked me out. I slept for 12 hours straight. Far as I'm concerned it's a miracle drug."
