Excess sleeping and laziness, even after doing regular exercise.. any remedy for reducing sleep hours?

Find why: Anemic? Depressed? Malnourished from a "pop" diet? Overweight? Sleep apnea? Porphyria? Hypothyroid? Any other symptoms? Dropped libido points to hemochromatosis / pituitary adenoma. Parasomnia such as restless legs? I had a colleague's career almost ruined by that one before it was diagnosed. Carbon monoxide? Early ms? Hypercalcemia? Don't treat the symptoms, man -- find the cause!
