cough
"This medicine is very effective. It not only suppressed my cough, but was a very effective expectorant. It loosened up my very tight feeling chest - an outcome the other OTC medications failed to provide. One caution:  I took a dose when I got up one morning, on an empty stomach, and then went out to do an hours worth of yard work. Came in and had a big glass of cold grape juice. Within 10 minutes I vomited the whole lot out. Felt better after a bit, though."
