I disagree with the fact that it lacks recreational value, as i have attained quite a nice high from it, but nothing compared to its bigger brother, pregabalin (Lyrica). Either way, shoot for approximately 900mg and see where it takes you, but remember this
1) Tolerance to gabapentin skyrockets very quickly, so leave 4-5 days in between trying new dosages.
2) Gabapentinoids have been known to cause extreme dizziness in some people, so you might get high, you might get really dizzy, or you might get a mix of the two like i do.
Be careful, and good luck
