For future reference, let the torpor (purple) bar go all the way down...and just before it runs out feed it however many it will take to make it go all the way back up (used to be like 80 torpor points per narcotic). Reason being, It takes longer for the torpor bar to go up, than it does for it to drop...once the bar fills back up it will not stay up any longer if you pump more narcotics so dont waste them...once you pump narcotics from empty, wait til it goes all yge way back up then all the way back down again...hope this helps in the future
