Cough
"I was taking Hydromet for pneumonia. It seemed to work quite well the first night, as I took it right before bed and I slept very well. However, I found that while taking it during the day, I got extremely nauseous and continuously threw up until an anti-nausea prescription finally came through. I usually do fine taking pill forms of codeine, such as vicodin etc, but find that in taking this during the day, it causes such dizziness that you feel like you&#039;re on a horrible theme park ride. Do not recommend if you are susceptible to vomiting from being too dizzy; seems to work for others though."
