Neurontin is one of those meds that takes time and lots of patience due to it's side-effects. You have to slowly increase the dose until you get to a workable level, yet each time you increase, you will likely experience a little more of the 'zombie effect', as I call it.

But once you get to an appropriate dose, the side-effects do wear off for most. If you're not working, you might have better luck in being able to tolerate it during this period.

Just pay attention at each dose to see if you get even slight improvement, so you know if it is helping. If yes, then move up to the next dose to see if you get more benefit, etc. The doctor will start you off low and give you some room to increase a little on your own or call for instructions to up the dose.
