"i have prolapsed disc at c7 in my neck and inoperable spinal stenosis. the pain is relentless and unbearable. i took various nsaids and co-codamol at maximum dosage.  the pain was still very bad. my doctor prescribed gabapentin. i started at 300mg, 3 times a day and as this took the edge off the pain, i decided to go straight up to 900mg, 3 times a day. at this level, in conjunction with the other medicines, the pain is now generally distant to tolerable which is fantastic, although the efficacy does tend to wear off a little near the time of the next dosage. ramping up to a high dosage so quickly definitely made me feel a bit tripy, as well as paranoid, irritable and aggressive but this has, thankfully, subsided over time."
