I have been taking gabapentin for about 10 years and it works pretty well for me. Have at times combined with amitriptyline, now combining with tramadol. This is a good first drug to try. I believe I get some memory problems and possibly trouble concentrating like I should be able to for engineering work.

I have heard of people saying that a drug stops working after a time. I am wondering if, in some cases, that the cause of this may be an increased level of pain and the perception is that the drug is not working as well.
