Zeeskite- Thats a gemara in Brochos on Daf Hey. It says you should have your yetzer tov fight your yetzer hora. if that doesnt work then learn torah. If that doesnt work say krias shema. If that doesnt work remember that one day you will pass on from this world. It appears to be as a last resort.
On the other hand, the Mishna in Avos (3:1) says to remember in front of whom you will have to give a din v’cheshbon.
