Most B complex vitamins are not worth much. The dosage of B vitamins is just too small. A B-50 or B-100 complex would be much better. Even with a B-50 or B-100, it is worthwhile to add B-12 methycobalamin. Most B complexes have cyanocobalamin.

TV is better than the computer in my experience. You are farther from the screen and the visual processing load is much less. If you are reading online and find you need to reread a line of text, it is time to take a break. I find high def TV to be a strain.
