If you're not achieving restorative sleep each night, your "sleep-debt" will erode your quality of life. It's impossible to treat if you aren't diagnosed. The first step is to be aware of the symptoms and then speak to your doctor. It's like catching any other malignant problem; the earlier the better. It's also equally important to look outward at family members, immediate and extended; whom you believe might have the symptoms mentioned. Advice from a loved one usually goes a long way.
