I know there's been much discussion and comparison between Neurontin and Lyrica, etc....

I simply want to know for those of you who have taken the generic form of Neurontin (Gabapentin).......How LONG does it take to show signs that it will actually help in diminishing neuropathy?

AND do you still need to take a pain med on top of the Gabapentin in order to get relief ?

I've taken Lyrica in the past, had very rapid weight gain, tooth decay.....
So am very leery of this Neurontin trial I am on, as I know it is a direct cousin of Lyrica, so I'm trying to stay at a lower dose.

Also, has it been to anyone's experience that 'you get what you pay for'?
Other words, is the Neurontin better quality and more effective than the generic form?

Thanks
