As for me I just take good old piracetam every day (for more than 10 years already, huge doses occasionally) and feel great. Sadly it is not and will never be approved by FDA as no corporation is interested in funding credible research. Emoxypine is another substance that can be good do take regularly (though in recommended doses only, it is not nearly as dosage-flexible as piracetam AFAIK) if your brain fails to get the amounts of oxygen it needs.
