I've had bad sleep patterns my whole life, being the uncontested World's Lightest Sleeper, now exacerbated by living with a relatively frequent snorer. My pattern for the past few weeks has been as follows: sleep restlessly if at all and wake up tired. Collapse into bed around 10:30 - 11. Even if sleep is achieved, wake up at 5 or so and find it impossible to go back to sleep. Therefore, become extremely tired and need to go to bed between 10:30 - 11. Rinse and repeat. Not as bad as insomnia so I won't claim I feel your pain but still annoying. Hang in there.
