There are several different ostensible Modafinil cofactors out there...
* Caffeine
* Grape Seed Extract
* L-Theanine
* Phenylpiracetam
* Noopept+Choline precursor
I've tried all of these, Phenylpiracetam is probably my second favorite but there's one cofactor of Modafinil that rarely gets mentioned which fits into a unique category as lifehack.
