Gabapentin

I was diagnosed with Bilateral Occipital Neuralgia around four years ago and it’s been hell ever since. I’ve tried several different avenues to get a hold on this and I’ve finally found some relief in Gabapentin. I’ve been on it around 30 days now and of course since it’s working so well I’m experiencing sadness, depression, etc. Has anyone else had this same issue with Gabapentin? If so, what alternative did you seek out? I’ve already emailed my neurologist about this; as much as I’m enjoying the relief from the pain, I just cannot backpedal on my depression progress.
