It never really became a routine for me, so not much change could be noticed. I also couldn't rely on IQ tests, as I'd always maxed out any I'd taken. The experience itself was interesting, as so many thoughts and images were able to come up, but it was said to not be so helpful with memorization or languages, and those were the main areas I was looking for improvement in. It may work wonders for enhancing pattern recognition (one of the hallmarks of human intelligence), but I already do quite well with that.
I'd originally tried it about 8 years ago, when I was 14. At the time I was also very into photoreading and lucid dreaming, so there was likely a lot of overlap in effects. It's tempting to give it a serious shot again, just to see what happens. At this point I tend to have some suspicion of the benefits of many of the accelerated learning techniques people promote, but they may simply take a bit of practice, and thus I don't discourage anyone from at least giving things a chance. Win offers many of the techniques for free on his site.
