Hey future reference! I've had a lot of surgery in my life, so I feel you on how hard it can be. I really think that you should give Gabapentinoids a proper shot before moving on to the next trial. Let me start out by providing a little research sample that might interest you regarding the concurrent use of Gabapentioids with Opioids. In short, it would appear that the former has a demonstrated ability to reduce the need for Opioid painkillers. This article concerns Pregabalin (Lyrica) specifically, but after a short trial of Gabapentin (Neurontin), you shouldn't have trouble upgrading.
I can say from personal experience that Pregabalin does reduce the need for Opioids. I'm only speaking of my own experience, but that experience closely mirrors this study.
You say that you're not experiencing any effect from the Gabapentin right now, so I really would encourage you to take a look at some of the stuff here on Bluelight and moreso on Reddit concerning the most effective ways of using it. It's bioavailability is effected greatly by things like having a high fat environment in the stomach or, making sure to space dosages out. If you have any questions dude, please feel free to send me a message and we can talk about it! Much like my sweet, sweet Lainee, you'll find my box is always open.
Pregabalin in the context of multimodal pain management may be associated with reduced opioid consumption and other medical complications in patients undergoing TKA, including previous users of chronic pain medications.

Painful One: I guess it shows how totally fucked up I am in the head when I say that I've always considered the psych ward sort of like an all-inclusive two week vacation. I would generally spend the time totally blitzed on a cocktail of Methadone/Buprenorphine, sedatives and even the occasional anti psychotic if I was feeling frisky. Speaking of feeling frisky, I also have met two separate love interests at detox/psych wards. Lara was definitely a keeper, but when she would drink she'd get a little crazy. Lainee was not a keeper in any way, but she was cute and she laughed at my stories and her levels of sheer insanity and machiavellian sociopathy made me feel better about myself. However, our love was simply too strong for the universe to handle. Also she would beat me and call me names like slut/whore/jew-boy

...but that's neither here nor there.
