I always remain fully clothed until the fasten seat belt sign goes off. I don't want to find myself having to run barefoot across a snowy, muddy field just west off the end of 27L or 27R at Heathrow.
Shoes on for takeoff and landing - absolutely.
Save the ambien for after takeoff - absolutely.
PJs or other sleep attire - really depends on the airport and time of year. I would not change into PJs departing YUL in January, for example.
