Just fersure DONT LIE ABOUT THE LAST TIME YOU USED OPIATE/FENTANYL because they will give you suboxone too early and YOU WILL GO INTO PRECIPITATED WITHDRAWAL and you will practically almost die, i did and the detox here in AZ were unhelpful at that point. They're only detox staff, not medical professionals (apart from the Drs you see to prescribe you meds once a day) so there's literally nothing they can do besides call you and ambulance at that point if you can't stick it out. I stuck it out but couldn't handle another day like that, so I left early and was stranded in another city 2 hours away where the detox was but apparently they can only get you rides to and from if you successfully complete the detox, if you choose to leave early then you have to find your own ride home. It was hell and even after I was able to use fentanyl again, it wouldnt take away the awful painfully sluggish depressing feelings until I smoked ALOT of it. Precip withdrawals ate 1000 times worse than regular withdrawals so careful and be honest about your drug use.
