Your pineal gland releases melatonin when it is dark. This neurotransmitter tells your brain and body to regenerate. When you wake up while too much is still in your system, you feel bad because you are busy regenerating.

The Short Answer

Your pineal gland releases melatonin when it is dark. This neurotransmitter tells your brain and body to regenerate. When you wake up while too much is still in your system, you feel bad because you are busy regenerating. After 7, when the sun starts shining, your pineal gland will be releasing seratonin, the same stuff that gets triggered for release by MDMA / ecstasy. Thus you feel better at 9 when your system has more seratonin.
