Not everybody gets withdrawals from gabapentinoids, I didn't despite abusing pregabalin at higher dosages than prescribed, but many do and when then it sucks. Of course, there is no way in knowing whether it'll affect you before it's too late.
These drugs have the steepest tolerance curve I've ever experienced with any drug and are only enjoyable when either taken way above your usual dosage or after a longer tolerance break. The recreative effects aren't necessarily related to the therapeutic ones and it seems to work for nerve pain even after one acquired tolerance.
Yeah, they cause brain fog, I felt kinda stupid on 600mg/d pregabalin.
