Pain
"Definitely effective against serious pain.  However the side-effect warnings are serious too.  This drug suppresses breathing and I was scared the first time I took a single pill.  Kept &#039;forgetting&#039; to breathe.  Ever since, I&#039;ve used a pill splitter to split the pill in half and this has proven a manageable dose.  I hardly ever take these, though, because I don&#039;t want to become habituated."
