Nootropics
Nootropics
Nootropics are substances which enhance mental functionality without causing harm.

     I tried ginko and unfortunately was quite allergic to it.  Developed hives, so took some benedryl which puts me to sleep and didn't repeat.  Substance I've found most useful are fasoracetam, prl-8-53, and piracetam, the latter though for tinnitus which for me it almost totally eliminates.  Faso for overall cognitive performance, and prl-8-53 for memory.
