Have you looked into the antidepressant medications? Many people get a significant reduction in pain from various antidepressant medications.

Of course, just like anything there are side effects which vary from person to person. But, it doesn't seem like they cause the "zombie" feeling as frequently as lyrica does.

I've been taking gabapentin 1800 mg/day for about 9 months. It's been working OK, but I may need to try something else soon. (Seems like its starting to wear off before the next dose is due - and I don't really want to increase dosage because I feel any more would make it somewhat risky to drive long distances.)
