So, looking into why I've yet to get any effects with I-Doser, and found something interesting on a forum about brain entrainment. Apparently, regardless of how you're going about it (Monaural/Binaural beats, Isochronic tones, etc), there are many people who sub-consciously reject the entrainment due to fear of altered mental states. It's called the gaurdian effect.
These people apparently have an extremely hard time entering a trance, and when they get close to one, their brain screws them up with intrusive thoughts, itches, fidgeting, etc.
Honestly, I don't think I'm afraid of altered mental states (At least not consciously), but I do have itches, random thought derailment, etc, while trying to dose and it breaks my concentration, probably ruining the dose.
I was wondering what others thought about this? Does it resonate with people who can't, or couldn't at first, dose? Or were you maybe afraid when you first tried it and it still worked? What's your opinion on the guardian effect and I-Doser?
