Don't worry about how long you stay on each step. The directions in the package are just a guide. They do recommend that you stay on each patch for a certain length of time in order to achieve good results, but if you feel you need to stay on 21 mgs longer, then so be it, it's not going to harm you in any way. Most people say they don't notice much difference when they do reduce from 21 to 14 mgs, but every one of us is different. I would recommend that you go with what you feel comfortable with, and if you feel more secure being on 21 mgs a little longer, or a lot longer, so what? As long as you are NOT smoking, that's the goal, right? And don't worry right now about the day you go off of patches for good, that should be the last of your worries. Just worry about today, take this "one day at a time", and you will be fine. And the Wellbutrin does work very well for depression from quitting, and I noticed it even supressed my appetite, which was great.
Congratulations on your 9 days smoke free, and whatever you do, DON'T SMOKE!!!

Good luck...
