Have you been having trouble sleeping? Exhaustion is your constant companion today. Staring wide-eyed at the clock in the middle of the night is no fun and does a real number on your attitude. If you're keyed up over personal issues that are robbing you of sleep, perhaps it's time to resolve them if you can. If you're worrying about situations beyond your control, you may want to try some light yoga or meditation before turning out the night light.
