    How in the world can someone claim that modafinil is a “cognitive normalizer”? Or even that it could be similar to nicotine in this respect? I know people who have been taking Provigil for 5+ years, and they STILL benefit from it. I don’t intend to be contentious, but I’m just wondering whether there is any evidence for this claim…

      Its just common sense. Tolerance exist with all drugs. After a while your body will adapt, if you take it everyday. Long term users should consider breaks here and there. 🙂
