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.
As always, it will be essential for travelers to arrive at the airport a minimum of two hours for domestic and three hours for international flights to allow time to get through heavy traffic, park, check in, get through security and navigate to gates. If you're checking bags, add some extra time on top.
