We're sorry to hear that! In our experience, it's less of an immunity factor and more that different brains require different inductions. Our projects' hypnotic aspects thus far have focused primarily on blends of audio, visual, and kinesthetic inductions, but if those don't work well for you, then e.g. a confusion induction may be more your speed. We plan on expanding our induction repertoire in future projects, and hope that some of those experiences work better for your specific mind!
