Zonegran anyone?

Noone in the pain management board knows so I'll try you! I have polyneuropathy and recently had a ulnar decompression and cts that turned into a 3.5 hr surgical fiasco with resulting nerve damage to the ulnar and median nerve in left hand, not Dr fault they just didn't think it would be such a mess in there as the tests didn't show that. I wasn't able to tolerate neurontin or topomax a few years back so he gave me zonegran as it is on the same line. I would like some hands on experience from real users not just what the PDR says or the pharmacuetical co information that would like you to believe.
