Yes, it is a challenge to withdraw from Gabapentin - I've done it in the past, so I can vouch for that. Not sure it's as bad as heroin, but it certainly is unpleasant. Unless your other issues make this an "emergency" withdrawal - make sure you go very slowly.

There are a number of other medications out there that may help, if you have a neuro that is willing to work with you to find the best option. Gabapentin is kind of the first line drug since it's side effect profile is relatively mild (at least for the majority of people). I hope your other issues resolve once you get off the Gabapentin, but don't get discouraged if it doesn't happen right away - some times these things linger for quite a while.

Best of luck.
