Bacterial Infection
"I was prescribed this drug for an ear and sinus infection. Within an hour of the first dose, I got a bitter taste on my tongue. But not just on what you think as your tongue. I can also taste it halfway down my throat. It&#039;s so bad I have to constantly chew gum, eat, or drink something strongly flavored. It also keeps me awake at night. I have to keep gum in my mouth, which I press flat and smush to the roof of my mouth. 

After five days and four nights, I finally cried uncle and called my doctor, who told me to discontinue the medicine. Unfortunately, the taste persists, and I&#039;ve now got burning pain in my esophagus. The good news is my ear/sinus infections are better, but clindamycin is going on my allergy list. I&#039;ll never take it again."
