I bought this because the cough medicine the doctor gave me ran out and I still had a nasty cough that kept me up half the night. Mind you this cough I had was a BRUTAL cough, so I figured the next best thing was Buckleys because we all know it taste awful, but it works! I took it at night time before bed because that was when my cough was the worst and found I still found myself waking myself (and the house) up coughing. As my cold got slightly better, I found that the cough medicine worked better.
Yes, I would purchase this product again, but only if its a mild cough. Otherwise there is no point in putting your taste buds through that!
