I've only tried regular modafinil, though I presume they're fairly similar. Didn't get any buzz or recreational effects off it, but it does what it says on the tin, keeps you awake^
i actually found that to be pretty fun... especially with some alcohol in the mix. or benzos. NOT RECOMMENDED - this is just from personal experience. Needless to say, i dont do stuff like that anymore b/c i'm an addict and it lead me down a terrible terrible path.
