People on the Autistic Spectrum may have huge desires for certain sensory parts to be stimulated.
(eg, scratching the head, white noise, heat).
But if you indulge in these sensory obsessions, then are you only going to make self more dependant on them and make your general condition worse?
If you go cold turkey, then it in the long run, it may actually be better for you, as it may re-wire your brain to diminish some of the other negative traits of AS such as insociability.
After all, these obsessions are just naother part of insociability. Not needing to obsess on something sensory, means you are better able to concentrate and engage in a social situation.
