Yeah, exactly. I take modafinil, and it doesn't make me smarter in the sense of "fluid" intelligence, it just gives me the ability to last longer on mental tasks.
I used to be completely mentally exhausted after a single meeting, modafinil fixes that for me. It makes me smarter in the sense of "crystallized" intelligence as a consequence of accumulating more knowledge, experience, mental models etc.
There's also the problem of getting used to the drug. When I first started taking it, there were various side effects (including perceived worsened short term memory), which subsided with time.
