I believe you mean Cuando, not caundo. There are also some accents and tildes missing.
I assume you know the meaning of your question. Are you supposed to answer in Spanish?
Possible answers might be that you have a cup of coffee, or take a nap. What do YOU do when you are tired in the morning? Make up your own answer and translate it to Spanish.
Caundo estas muy cansado por las mananas, que haces?
