Hmm...I take the following herbal supplements and vitamins pretty much daily:
Red Chinese/Panax Ginseng
Eleuthero/Siberian Ginseng
Gingko Biloba
Vitamin D
Vitamin B
Damiana tea
I've had problems with chronic fatigue (at the worst point, before I took the supplements, I'd fall asleep every two or three hours) ongoing for several years, coinciding with psychiatric treatment (which I'm getting out of ASAP; bad experience altogether); apparently I enter dream sleep at an abnormally high rate and that stops me from getting proper rest. But the ginseng helps with fatigue and staying awake and the damiana gives me a slight general motivational boost.
Reading everyone else's posts is inspiring me to do away with the other unhealthy stuff I consume. Too much caffeine and processed junk, I think, which doesn't help things either.
I've also got a ton of other herbs I keep on hand for other things, but the above's my daily regimen.
