How often do you wake up in a terrible mood? Ever wonder why that might be the case? Here's three reasons that might explain it. This, according to science...

1. You are eating too much crap. Vegetables and fruit are natures way of cleansing and making you less uptight. Eat more veggies, feel better. Period.

2. You are not getting enough water! Drink a ton of water and you'll feel a difference almost immediately.

3. Facebook is another way people are getting too cranky. Seeing others have better days than you is a real downer, plus the non-face-to-face interaction is no replacement for the real deal.
