cough and nasal congestion
"I had an experience with a rare side effect. I began sweating profusely after taking the pill (recommended dosage) after 3 days.  After reading further, I have figured out that I drank 2 cups of coffee the third morning when I took the pills, which led to the sweating.  Otherwise, I have had no adverse side effects, and it works great!  It is just not a good combination with coffee!"
