Oh yes, you need to enforce rest time, even if they don't sleep. You deserve a break! I have 3 almost 4 yrs olds (4 if you count my own) and they all MUST lay on their beds in another room quietly and watch a movie (with the lights out). They are not allowed to talk, and if they are disruptive then they are moved to another room to lay down and miss out on the movie. This gives you a good 1 1/2 hrs to relax
