I was just prescribed neurontin (gabapentin). Is it more effective if I take with or without food?

Doesn't matter. Neurontin or Gabapentin is not dependent on whether you take it with or without food or even what types of food. This study (http://1.Usa.Gov/n5ysd2) actually looked at this issue and did not find any statistically significant differences. Best to take as directed by your doctor. Neurontin/gabapentin generally is best when taken in divided doses throughout the day.
