For Cough and Nasal Congestion "I’m only giving this a high rating because it did relieve my congestion and non-stop coughing. However, shortly after, I started having extreme anxiety, feeling like I was jumping out of my skin, and diarrhea. Maybe everyone doesn’t have the same side effects, that’s true, but this part was awful and would prevent me from taking it again."

For Cough and Nasal Congestion "I took two tablets at 9 am yesterday, followed by about 5-6 bottles of water. Sure, the congestion and cold went away significantly, but I could not sleep 'til about 4:30 am! I work a 12-hour shift and had to call out from work. Needless to say, this medicine is going in the garbage. Heart palpitations, anxiety, and insomnia!"

For Cough and Nasal Congestion "Worked alright for relieving some sinus congestion, but did have an effect on my plugged-up ear. However, the anxiety is awful and pretty severe. For this reason, I will not use again. NOT WORTH IT."
