Tramadol
"I was prescribed this medication for chronic severe neck pain.  I was taking 50mg per day.  While it worked to eliminate pain, I experienced constant nausea, vomiting, light headedness, and many symptoms of serotonin syndrome since I also take celexa each day.  Seroonin syndrome is serious and dangerous and can increase the likelihood of seizures.  Also, I'm taking this medication at night and it keeps me awake all night instead of allowing a good night's rest.  "
