I have done this flight.

I believe that there are two approaches worth trying.

Option 1: go to sleep immediately after take off and do not bother with breakfast as it is only a short flight

Option 2: maximise the experience and stay awake for the whole flight (if you can stay awake until 5 or 6 in the morning UK time) and then sleep in your hotel.

I am sure that your hotel in DXB will provide an excellent bed and a tasty breakfast.
