i just started afew weeks ago on neurontin ,100mg 3X aday, I was suppose to , on my own ,if didn't see any results to up it to 200mg 3X day, but, I wonder about it, taking them for severe sharp pain that strites up in my head daily serveral times aday, the 100mg 3X times make them bearable, but, isn't it just candy-coating the problem, sure I could raise the doseage, and not feel the pain as hard, but, "I know" I am still haveing the pain, so all we're doing here is covering up the problem.....right?? Not looking for surgery, just want to fix the problem. And how does taking the pills "fix" the problem..??? And yes, with some of the others , I have really put on the weight, since the pills, 13 pounds in 4 weeks. And I am already over-weight, don't need this.
