Hi,Marycain. I've been on about 1800mg a day for a while (not sure if that's 'max' or not - seems like a lot.) I am experiencing some break through pain again. I'm working with a physical therapist who thinks some of my problem may be mechanical, but I'm not so sure. The numbness in my leg is actually worse. Anyway, I think you may be right - the medication isn't as effective after a while. I had absolutely NO break through pain for quite a while. Now it's back - not all the time, but frequently. What IS the maximum neurontin? Is it different for each of us?
