My wife seems to have this but nothing we've tried helps. She wasn't always like this, prior to my meeting her, she spent a few years working at her family's restaurant where her daily schedule would be something like: - Wake up at 10:00AM - Go to work by 11:00AM. - Get off work at 10:30PM. - Eat "dinner" at around midnight-1AM. - 1AM-2/3AM is free time. - Go to sleep at 3AM, rinse repeat. She was not like this when she worked an office job (fashion designer), but now she can't get back to a "normal" schedule.
