That's mine now as well. I tried many, many times and anything at night that is less than 8 hours just turns me into a mess. Too many flights from SEA or PDX to ATL, getting 3 hours of sleep and then being completely useless the next day.

If I absolutely have to take one, I will only fly up front and try to have take off as late as possible and fall asleep fast. Dress in something warm, soft, and comfy. Of course all of my TATL flights are overnight, but those are long enough to get some sleep and be somewhat okay the next day.
