Lyrica helped me with the pain, but I had some silly side-effects, like Khiba it made me feel stupid, and I noticed that I was getting frequent chaps in my lip, so I too weaned myself off of it, but I spoke to my neuro also. It's trial and error as Khiba say's, but if it worries you maybe you should take to your neuro/doc.
When I was taking Lyrica, missing one dose did me in too! When it wore off , the symptoms, such as nerve pain for me, came raging back. I finally weaned off it and feel much better even though I cannot move as easily. I can see much better now as the Lyrica affected my eyesight. I think it also made me feel stupid.
Now I do very well with a combination of low doses of valium and baclofen. I think drugs work differently for different folks. :) Its a trial and error process of finding what works for each person. :)
