Nausea/Vomiting
"Got this prescribed to me when I had a bug a few months back. Recently I have had recurring Clostridium Difficile (infection in the stomach) for a few months. I take Promethazine when I feel nauseated and it always works in about half an hour. It makes me extremely tired, but its worth it if it combats the nausea. That being said, it doesn&#039;t work for any stomach ailment other than nausea (pain, cramping, bloating). I love knowing it&#039;s around just in case I need it. (PS if you are really going to throw up, it will come out the other end after promethazine.)"
