Do you feel groggy throughout the day? Well, have you been missing sleep? It’s an obvious connection: When you don’t get sleep you feel tired. When you’re tired you don’t have energy. If you’re feeling lethargic and lazy throughout the day, it may be last night’s fault. Don’t let a lack of sleep ruin your routine. Consider adding a sleep aid supplement to your diet if you have trouble finding sleep as your head hits the pillow.
