I felt I had to take some painkillers to get some rest / sleep this afternoon, so I took two Cosalgesic and got 2 good hours' sleep. When I woke up, I felt by no means 100%, but better than when I fell asleep. I got worried then about addiction to these things since yesterday I had a new "nauseous" pain in my knees. I Googled "painkiller addiction withdrawal cosalgesic" and read two articles. Now I'm really worried that I should stop taking them. See http://trusted.md/feed/items/system/2007/06/17/the_old_ladys_friend and http://www.essentialdrugs.org/indices/archive/200502/msg00000.php. This particular tablet has been banned in a few countries. It's also known as Distalgesic or Dolorgesic.

http://www.spine-health.com/topics/conserv/painkiller/painkiller01.html mentions some symptoms of painkiller withdrawal. Of the ones mentioned, I have muscle and bone ache, sweats and insomnia, and had these coming out of the first op too. :( I guess I'll just have go back to DVDs and games to keep my mind off the nasty feelings.
