My regimen is to lay my head on a woman's firm breast for several minutes. It does wonders for your circulation.
Have you tried vinpocetine? It is supposed to be good for protecting the myelin sheath and helping oxygen transportation to the brain. I definitely notice a difference when I take it.
are you sure your adrenal glands aren't burned out? On average how much caffeine do you drink per day?
my concentration improves alot within a week when i cut down significantly on the caffeine, sodium and sugar.
I wouldnt try any herbs or compounds that have not been tested rigorously. A popular weight loss pill 'hydroxycut' is running into some issues...
