Funny, I am on gabapentin, also called neurontin. It is used to treat a variety of things, including epilepsy, nerve pain, anxiety, and others.
I understand it to be quite harmless unless you have kidney problems (which I have, and the doctor "forgot" three months ago). I ended up having a toxic reaction which was awful, it was really scary. But that is just me...
Interesting that you are using it for anxiety. I wonder what dosage level is used for anxiety. There is a wide range of dosages.
I hope you get the relief you are looking for, and you deserve.
