Has anyone been prescribed this?

I was prescribed Gabapentin 100mg for nerve pain but when I researched the drug online, it said it was an anti-convulsant [controls seizures]. Should I take them? I'm afraid that since I don't have seizures it's going to cause me to have some and I feel like it's pointless to take it.

I also read it could be prescribed for anxiety attacks and nerve pain.

Just want some people's opinion on the drug, how it makes them feel [does it make your anxiety go away?] and what the side-effects were. Thanks in advance.
