What Is Super Sensitive? in Super Sensitive People Posted June 22, 2015 · Report to Admin I would like to say also, that if one has been sick a very long time, it can take more than 6-12 months. The situation can be complicated with other food intolerances or results of the illness. I had been sick for 30+ years and still felt I am transitioning after 3 years. I don't want to discourage anyone making them think it will take that long, but only explain that sometimes it does.
