Anybody know anything about Cognition-Enhancement Drugs? Has anyone tried any? Which ones work? Should I be concerned about using them? Where can you get them?

That's a large area of study. Noone knows how to brain works, so, certainly noone here will.

Look up chemicals that enhance/increase/reduce reuptake of neurotransmiters.

Personally, I think lots of water, exercise, and the proper amount of nutrients will give you the best results.

whatever you do don't quote me on this but the "smart drugs" are just properly controlled amphetimines. I don't have "normal" bio-chemistry but when I take some perscription meth I fucking fly through a math test and other stuff.
