Rob,
The place you are at, the last 10mg, is always accompanied by lack of sleep and restlessness. Totally normal. And you may find that it takes a few months to get to 0. No worries if your doc will allow it. It's just very, very hard.
See if your doc will Rx something for sleep. When going off of pain meds sleep is the very last thing to return to normal. It can take up to a year. You may need the added support. Again, it's totally normal.
I am stopping my Ultram. Over the weekend I've gotten down from 400mg daily to about 200-300 daily, and I expect to be off by next weekend. My system is buoyed by other meds that do essentially the same thing, so it's not like I'm suffering heavy WDs, or anything like that. I think my other pain meds will work better w/o the Ultram.
BTW, nice work.
