pain
"This medication worked very well to ease my ankle pain.  However, it left me feeling a little forgetful after taking it for a few days.  It also made me very drowsy.  But I was not in the severe pain that I had been.  The most negative reaction was when I stopped taking the medication.  The following day I felt nauseous, shaky, dizzy, and had the cold sweats.  The withdrawal symptoms were very unpleasant."
