Yes, you can do it alone (although it's not for everyone). I was up to 20 percs a day at the end of my addiction. Granted, I was using recreationally, not for pain. As well, I wasn't dependant on the diverse cocktail of pills that you are. That being said, I quit in 4 days, on my own, without telling a soul. I continued to go to work, and I live with my finacée. If I did it, you can too, but tlewis27030 said, you should have a plan in place to deal with your physical pain, because living in contstant pain is no way to live. Good luck, and keep us posted on your progress.
