Nearly all the paraliminals you only need to use once (per side where the sides differ).
There are a couple of paralimials that are handy daily for a week like the Smoking, Weight Control, Memory Supercharger, Personal Genius.
The others you use once then see what happens Like the Belief paraliminal, you work on a belief and then notice how it's changed if another limiting belief has surfaced then you use the paraliminal again if you want to work on that. Used progressively they can be used daily however it is not 'required'.
