I've discovered all it ends with Nutrition, proper consuming of the food, right amount and right intervals, courses if you will, I was a computer technician and used to eat cold pizza heated on a 17 Nec monitor and hack I didn't know normal man suppose to get vitamins. I have learned an expensive lesson, take care of your health, take the signs seriously, and deal with the issues in timely fashion.
