I started with 100 mg of Gabapentin at night and slowly started to increase and was up to 2400 mg at night. Each time it would work for a few days and then stopped having any effect. And eventually 2400 mg was not doing any good. I added 30 mg Duloxetine to the mix and that was good for a couple of months. Then that stopped working too. Increased Duloxetine to 60 mg and so far it has been effective for the past 4 months. i have slowly started to reduce Gabapentin (100 mg every two weeks). I am down to 1500 mg of Gabapentin a night along with 60 mg Duloxetine. Let's see how far I can take this. Fingers crossed.
