Hi parasync-
Good question. Here's what to do.
First off, I don't recommend that you do more than two paraliminals during a given 3 week period. However, you can do a maximum of 3.
Now, when I say alternate, I mean, switching back and forth. If you did "Self-esteem supercharger" today, to "You deserve it!" tomorrow. If you do two in one day (which is what I did, one for a mid-day lunch nap, and one before bed) Do both in the same day.
Keep it up for 3 weeks, switching back and forth each time.
Let me know if you have any more questions.
