I take it as a medication with CRPS. I take 900 mg morning and 900 at night for allodynia. I also take opiates for the CRPS. I have never heard of pain patients using gabapentin to get high with the pain meds (as stated above)....I can't see how, as I have never "noticed" this medication other than it making me sleepy on higher doses.
It's interesting....my pain mgt. doc, before realizing I had CRPS, told me he didn't want me on Gabapentin, because it was a "nasty" medication, then when he realized I had CRPS, he wanted me to take "as much as I could tolerate." He doesn't realize he told me this years back, but I've never forgotten. I dont care for the sleepiness, but it does help with the allodynia. There have been times I tried to take less and the allodynia got significant...too significant, so I determined I needed this medication and keep taking it.
