@pacodennis I am fortunate to not have the side effects of Gabapentin that others have, not after 6 years anyway. But yes, I am reluctant to call it "withdrawal", but the pain when I forget or delay a dose of Gabapentin is definitely noticeable, and it improves again in about 1 hour after taking it. My internal PN pain can't be relieved by tylenol, as a hospital tried once when I was admitted for an unrelated procedure and they were "out" of Gabapentin (?). Those 2 days were unimaginable - not traditional withdrawals you read about in magazines, just the return of awful pain, which confirmed for me that Gabapentin worked to curb, but not cure, that symptom. That taught be to always carry extra pills with me in the event I'm caught off-guard again.
