It was a trial and error for me, with the suboxone's and IVing them. The first time I shot a half of a sub strip the day after doing a good amount of heroin, I went into crazy instant withdrawals. Now, I was aware of this, but it being my first time... I didn't know what to expect. I timed down the length of the withdrawals, and noted how I felt after. It was about 20-25 minutes for the chemicals in the suboxone to bind to my opiate receptors. After that awful withdrawal, I did that to myself a couple more times. I do not recommend it at all.
What I do recommend, is to take a piece sublingually, if you're in opiate withdrawal. Wait about an hour, then you can shoot up the suboxone. The chemicals need to bind to your receptors before you start to feel 'better', or 'normal'. I've done this through trial and error, and I'll still sometimes to this day.. put myself into instant withdrawal because I know it'll only be 20-30 minutes. Those minutes are horrible though.
