"SO MUCH PAIN! 
In the last 2 years I have suffered with a brain tumour so have been in a LOT of pain to the point of morphine everyday for a year. Then I had brain surgery...but the pain from this pill came pretty close!! In serious pain to the point of blacking out hot and cold shivers and just sat in pain feeling like trapped wind/indigestion it's just.. Ahhhh!!!! Don't take this!!!"
