Propecia pacing?

[Eric5]

Has anyone heard of propecia pacing where you go on and off with propecia so that your body doesn't get used to it and its effects wear off? If so, how long do you stop for, for your body to lower its tolerance?

I heard one guy that did this for sides and apparently it worked.

As I understood 10 year study, propecia should not lose effectiveness, there should be no real tolerance build up.
