Paroxetine
"My doctor weaned me off of Paxil a few weeks ago as it wasn't working. Three days after the last dose was the start of the two worst weeks of my life. It included migraines, nausea, decreased vision, when I turned my head or moved my eyes there was a whooshing sound in my head accompanied by extreme dizziness. Then there were  the bouts of crying for no apparent reason. In summary I would call this poison not medicine."
