I have had instant and permanent results, sometimes surprising ones! And somtimes I have things that I need to keep working on. It probably depends on factors such as the complexity of the issue, how well formed my intentions are, etc. Much of the time I can get good results with only a few sessions, using one or a mix of paraliminals.
Follow your intuition when choosing which ones to use- even if it does not make much logical sense- your unconsious mind is very wise.
I have to say that as a mental health professional, I have a great deal of respect for what goes into these recordings and programs. Very high quality and well thought out, with methods and technologies that I use and agree with. And as a consumer, this is one of the very best toolkits I have found for my own use- effective, inexpensive, and a lot more convenient than finding a trusted colleague to help out. (Still, the realy big stuff deserves professional one on one, sometimes)
Hope this helps
