Yes, I try to to do that. Recently I was on one month strict gluten-lactose free diet. Healthy overall but made nothing to my symptoms. It looks like what happens to me is a kind of self-dependent process inside my body. The only two things that I think make my sensory problems worse is an alcohol and even the minimal physical activity. So I avoid both now and not so happy about it (well, alcohol is not something one should seriously miss, but regarding the physical activity it is a real personal disappointment for me).
