I don't know if your claim is true but the past few weeks i was doing 600-1200mg 3 times a week with diazepam (valium) and couldn't really get high off pregabalin.I used to abused it years ago but last i tried my tolerance was like , already very high.I was wondering if pregabalin tolerance can go back to zero.But like alcohol and benzo it may have a permanent thing at some degree
