Thanks everyone for your comments. Okay, the tapes I have are Self Esteem supercharger, Personal Magnitism, NBG, Prosperity and Memory Supercharger. The first week I tried 3 of them out, and when that didn't show any results I then focused on one tape at a time, which didn't help either. I would not describe myself at all as analytical - in fact I'm quite the opposite - I took a very positive approach to using these tapes and only started to feel a bit apprehensive about them 3 weeks later when I knew, deffinately, that there was nothing happening. All other self help stuff has had a noticeable effect on me after using them, which was why I was surprised that this hasn't done anything.

Thanks
Angela
