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.
Step 2. Plan to arrive at least three hours before your flight's departure, especially the first time you fly. Seasoned travelers get a feel for airports and begin to cut it closer, arriving with the bare minimum of time, but chances are that you'll get turned around a few times at a huge international airport.
