Water, sleep, calcium, and potassium. Drink lots and lots of water. Take your body weight and drink about half of that in ounces a day. Also, get into a regular sleep pattern. If you can't get enough at night, try to take regular naps. I like to call them "cat naps." Also, drink a glass of milk and eat a banana a day. This should give you the calcium and potassium you need to keep twitching away. (All these things are crucial if you're prone to muscle cramps as well.) Also, stress can be a major factor. Try to schedule "personal" relaxation time...such as a soothing bath or a cup of warm (not hot) tea with lemon and honey while sitting by the fireplace or gazing out a window. Try to avoid sitting too closely to the TV or watching TV in the dark, as this causes strain on the eyes. When reading books, do so in a well-lit area, preferably with the light coming from behind. And this is the ultimate bummer for some of you, but staring at the computer monitor for too long of a period of time is damaging to the eyes. This causes major eye-strain. It also causes near-sightedness. You have to remember that our eyes were meant to be able to see far away as well as close-up...ancient people relied on the same eyes we have today to scour out into far distances in order to hunt for food, but in recent times, we've forced our eyes to not really see anything but a screen less than two feet away. This is why it's imperative that one glances away from the monitor every now and again to prevent myopia, and other such eye promblems. In recent times, we've forced our eyes to only see close distances when they are meant to see all around. Also, I recommend taking a multivitamin a day as well. This is wonderful because most people don't get adequate enough nutrition anymore, since most peoples lives are very active now days. Hope this helps some.
