What works for me is to take a nap for just one hour. No more. I unfortunately cannot sleep on the airplane unlike so many others and find myself so weary that first day when the plane lands in the morning. But if I can get that one hour of sleep in the afternoon of my arrival, I feel invigorated and then can enjoy my first evening in Germany (or wherever I am) and then get a full night's sleep.
