I swear I realized coffee is good at good t making me more productive even when I am depressed. same thing with things like ginseng and b12. the down side to each is that I have to stop taking them for them to regain effectiveness because they lose it over time.... but what if I switched them by week.. i.e one or 1-1/2 week coffee.. 1-12 week b12.. and thus o with the ginsing... I am kind of curious to if anyone has tried this to be more energized and productive. just curious.
