Wife Morning Sickness Help?

Ok....about 10 weeks in shes sick every day all day with nausea and blahness...She does the ginger ale and crackers before she gets outta bed, and when i go to lunch i always save he the ginger off my sushi ( i hate the stuff). Anyone have any ideas about what to help, she works a 60 hour week in real estate and wont take time off, she comes home at 8ish eats falls asleep and wakes up sick and nauseated..Should i tell her to take it easier or let her go and be happy and sick at work...and any tips to help her nausea as well :)
