Yeah - Nurse in ICU -
Can be rough. Wake at dawn... up all day with kids... got to work at 10pm instead of bed... try desperately to stay away till 07:30am come home and go to bed. its 27 or so hours awake in a row.
coffee... coffee gets be through... waiting for the sun to come up..
Hell!! Kudos to you. Nurses, teachers, paremedics... What careers.
