This is just a guess, and I'm not interested in your money, but I think that you probably have a health problem. I'd suggest you check out the book "The Mood Cure" by Julia Ross, which has some very good information on supplementation. Offhand, you sound like the author's profile for low-in-catecholamines, and might benefit very quickly from fairly low doses of certain amino acids such as L-tyrosine.

I strongly recommend reading the book, though, as there are quite a few caveats regarding self-supplementation like this. Using too high a dose can be as problematic as too low, and times of day are important too. Consistent management is important, too. When you're low on something, taking what you need can make you feel euphoric, but when you have the right dose, you won't notice anything by taking some. (Instead, you'll notice if you go off it for a few days, and find mood/energy going back to pre-supplementation levels.)

Anyway... don't know if it'll work for you, but I do suggest you try it. (And the same recommendation goes for anyone else who's experiencing a chronic mood or energy issue that's not specific to a particular task/subject/environment.)
