Suggestions for cognitive dysfunction/trouble concentrating?

[Guest guest]

Hi,

Outside the core protocol, can anyone suggest an herb, drug, or practice for

combatting

cognitive dysfunction, especially difficulty concentrating/fatigue when reading

and writing?

Any feedback on the relevant supplements listed by Buehner (huperzine,

vincamine, LAC,

zinc)? My LLMD mentioned Provigil, but apparently it's only covered by insurance

for

narcolepsy.

Thanks,
