Caffeine is my best friend. I've had the hardest time not feeling tired all the time. I constantly reach for coffee or an energy drink to get myself through the day! I eat well (I mean, I do have the occasional slice of pizza...), get enough sleep, exercise...The whole bit! I know I'm not as healthy as I could be, but I find it hard to find any sort of energy no matter what I do throughout the day. Any suggestions?
