Provigil (modafinil) worked really well for me. It increased my IQ by what I can describe as putting masses of ideas together for a fast conclusion. Instead of pondering, you get to the point. Only downside was that speech was impaired a bit, reached tolerance quickly, and I could not get to sleep. First one can be solved by a dopamine agonist and some form of piracetam, second can be solved by cycling it, and third is solved by ambien.
I tried an Indian generic version of modafinil and undoubtedly it was less effective and had harsher downs.
I'm posting this to see if anybody knows of either a.) a source of real brand name Provigil (Cephalon) or b.) high quality generic Provigil made by reputable company.
Thanks for any help.
