I didn't wan't to post an until some time passed. So far I've managed to retain the new mental perspective. There were a couple of lapses but they were very obvious and caught right away. So far the experience has had mixed results. Analitical thinking is a bit harder yet my mind feels overall clearer but the change is not in any way extreme.
About NLP. It doesn't have much to do with this experience. I just used the ideas of NLP - being able to work with your mental frame - the result was intresting.
Here is some info on NLP.
