Usually anything even in a pinch, but also 5,7, 21, 35, 45, also count. That seems like a lot of numbers, but that within itself can be obsessive. What types of actions get what types of numbers. I love to do things in 10's. I count doing something ten times and ONE. then I continue the repititions til I reach my preapproved list number. I may increase it if I do not feel it was 'enough' also.
