C.T. writes, "I had the worse head cold ever.  I had tried all of the usual over the counter remedies and nothing seemed to work.  One night, I couldn't stop coughing and desperately needed some sleep.  I applied Unker's and before I knew it, the coughing had stopped and I was able to get a good night's rest.  Now, I go to Unker's first.  It works and it works fast."
