I was taken off by rapid detox 20 years ago and put on Suboxone.  Then was addicted to the Suboxone and then back on methadone.  The methadone was originally after back surgery. I have had 6 back surgeries and with every one I would be back  on oxy or Percocet or other opiates.  
Then back to Suboxone.  It has been a roller coaster.  I want off the methadone and hydrocodone without the Suboxone.  The withdrawal of going off on my own have been awful.  That is why I want to do the rapid detox.
