I am late coming to this thread, and I hope that the 100mg is providing some therapeutic benefit to you. Gabapentin works for me for both mild pain relief and for anxiety, and I take 300-900 mg. per day, which quite a bit higher than your dosage. I do find that Gabapentin has caused me some memory issues but is effective for me, and I refuse to consider benzos for my anxiety. I also practice Cognitive Behavioral Therapy to assist with my anxiety issues. If there was another medical option available to me, I would consider it, but I am coping alright with the side effects for now.
