How many feedings does she get from the time you're home with her in the afternoon, evening? I used to try to smoosh an extra feeding in that time. I understand and remember (and shudder at) the need to function. You're smarter than I was though, I never managed the "sleep when they sleep" approach, which is really the only sane way to go, particularly if you have to deal with humans you don't love, during the day.
