Tapentadol
"It seemed okay. I was more alert than when using oxycodone. After three weeks, the side effects outweigh the positives. It was more psychotic than I had planned. After the 75 mg dose wore off, the drop off was steep. I felt very agitated and somewhat aggressive. Similar to prescribed amphetamine or steroid. It makes me so agitated that I have decided to go back to the Oxy. I also experienced some respiratory distress and diminished vision. Good try as an alternative but it is not for me. Kadian had similar reactions."
