Great information.  I just recently started using ashwagandha (from the Gaia company, liquid in capsules which I cut in half at this point) and I take 1/2 cap at night before I head for bed.  I usually watch tv for about 1/2 hour or so and then turn it off.  I know I shouldn't do that but it helps me sort of settle in for the night, or it seems to.  At some point I may get around to just not turning on the tv at all at night.
