Each time I needed to lose the baby weight, I stopped eating after 6:30 p.m. five nights a week. The other two evenings were reserved for nights out. Most of what I'd eat at night was junk food anyway, so it took only two months to get my pre-baby body back..
As a general rule, arrive at the airport no later than two hours before your domestic flight is scheduled to depart. This is somewhat later than the typical suggestion of three hours for an international flight.
