Personally, I find that once I gain the benefits of a certain intention to use a particular paralim, then I no longer feel any need to keep listening to them for that purpose.

For example, listening to Sales Leap for a couple of weeks helped me to overcome my public speaking fears, and the benefits are permanent. I no longer listen to that tape for the same purpose, because it has already helped me integrate a change of behavior and personality.

So, I guess what I'm saying is that my experience with paralims is very different from Don Juan's. All my changes are permanent, and I move on with my life having reaped the benefits.

Perhaps the difference is in what the user expects will happen? That is, if you expect the benefits to last, they will. But if not, then they won't. As I'm learning, in life, you create your own reality.
