I have only taken gabapentin, but it definitely helps me a lot. I also have another neurological disorder that it helps so I get a double whammy of help. Anyway, I know that everyone is different so I can only tell you about my experience. My PM increased my dosage of gabapentin to 2400/daily, but I first started on 100 mg. many years ago. It does have some minor side effects for me, but I have decided they are easier to deal with than the pain.
I hope someone else can tell you about their experiences.
