Yup! That's what I'm on. Gabapentin is my nerve blocker. They tried the steroid shot to the spine at one point. I was the chosen 3% to end up with a uterine hemorrhage from it during my next period that lasted 36 days. Lead to anemia and delayed a surgery.  I've got the tens unit and use it three times a day to confuse the nerves that are needing the pressure off them. It's an amazing little thing. My next surgery will be a laser discectomy to try and get the ruptured parts carved down enough to stop pressing on nerve roots. It's got a fairly high success rate according to the doctor. As for the 36 hour person- ouch! I am not sure what I was on during the first few weeks. My memory of that time isn't really there. I suffer short term memory loss as another side effect from the injuries I sustained so lots of things never make it to the long term part! But I do remember feeling sick and shaky for a bit once I was off IV stuff. I refused narcotics once I was able to talk coherently and discuss other options.
