Regardless of how much sleep I get, I seem to be tired quite often and usually when I have no business being tired. On average, I get a decent amount of sleep - usually seven hours a night. But often, I feel tired in the morning and today, while at work, I felt like I wanted to go back to bed. I exercise a lot: usually three or four days a week, but I don't have the greatest of diets. I'm just wondering if there's anyone out there who always feels tired.
