Precipitated withdrawal has always been the major deterrent to quitting/using Suboxone. Once the transition was made, I have had periods of sobriety. I had one particularly bad incident 2 years ago when I was administered Vivitrol despite my assertion that I still had Suboxone in my system, which resulted in an ordeal of 12 days of peak opiate withdrawal.i I have been extremely gun-shy about quitting heroin since that incident.
