I frequently kick on suboxone, and I have never been on a long term plan. In fact, I kick on ONE 8 mg pill, and I have a 2 gram a day habit. It's not easy, but it's done and over with in a week. I never stay on subs for more then 8 days, and never less then 4. I take 1/4 on my first day - I wait as long as possible, I aim for 36 hours. I then just wait until I can't bear the wd symptoms and continue to take smaller and smaller pieces. Eventually, I don't even realize that I haven't taken it in awhile. Again, it's not easy at all. I also find suboxone to be incredibly temperamental. Sometimes the detox is painless, I stop taking subs after 4 or 5 days, and I feel relatively fine the days after I stop taking suboxone. However, sometimes the detox is incredibly brutal the whole way through. And sometimes, I'll be able to handle the suboxone relatively okay - but once I stop taking it, I get violently ill for 2-3 days, just not AS bad as the cold turkey approach. In most cases, the one wd symptom I can't get rid of while i am taking subs and after for almost 2 weeks is how cold I am. And in most cases, after i stop taking suboxone I will have a few days where I absolutely can't sleep - the leg kicking, the feeling that every position you are in - is absolutely unbearable.
SO. I would say, your method is more then possible, and I highly recommend it. I would taper off the suboxone as much as possible until you stop. Taper it off so that on your last day - you are taking really small pieces, even crumbs. I don't think it really matters if you take it the 10th day or not. I think the important part of this is the taper. Always take a smaller piece then the day before. Don't take any more until you get sick again. Keep doing this until you aren't taking anything, or until you run out. The more you taper the less painful the days after will be. And even though you aren't addicted to suboxone yet - you still might get sick when you stop taking it. Be ready for that. This is why I would suggest not focusing on this 9 or 10 day thing, and just making one or two pills last 5-8 days, or 10 if you want. By the 7th day or so, you should be taking 1 mg or so and only every 24 hours....good luck.
