I guess it depends in part on your approach.  I promote dietary and lifestyle changes as a means to treat chronic illness, which isn't subject to the same regulation as "medical" stuff. If you want to create medical stuff, then you are talking heavy regulation. If you want to create or promote alternative stuff, you are likely to face less regulation.  Study after study after study shows that chronic illness is significantly influenced by diet and lifestyle.  Encouraging dietary and lifestyle changes to promote wellness is usually not considered "medical" per se.<p>My current plan is to work on better ways to share my mental models and experiences/practices so people can more effectively implement lifestyle changes and protective practices that work for me. To that end, I intend to write a simulation at some point -- aka a game.  I doubt I will run up against any medical regulation in writing a game as a means to promote health and wellness education.<p>FWIW:  Tinnitus can sometimes be treated successfully with chelation and supplements.  (Magnesium comes to mind.)
