All the titles are good. It will depend on your purpose. What you are trying to achieve.
As for the effect being permanent. Fortunately nothing is permanent, what we see as an improvement now can wind up being a limitation in the future 
They tend to be growth cycles and you can notice immediate results and then appear to go backwards for a time, often thats a reslut of other things showing up that we managed to hide from ourselves.
We need to remember we're not broken and don't need fixing. We are growing as individuals and things like Paraliminals are like training a climbing plant to help us grow in the direction we desire.
