I don't think my FAQ is appropriate for the top-level, as DNB is to me still in the twilight zone of effectiveness - unlike, say, melatonin.

Part of the problem is that the academic research (specifically Jaeggi 2008 and Jaeggi 2010) is flawed (see the Moody section of the FAQ), and the time consumption is massive: I'm willing to stump for melatonin because the time consumption is 1 or 2 seconds a day and the effects are clear; I'm not willing to stump for something with unclear (if possibly much more valuable) effects and consuming on the order of 20 minutes a day.
