Mixing an elimination diet with RR

I suffer from severe IBS...I bought a book that discussed elimination of certain foods...I have tried to mix it with RR...I failed in both...eliminating certain foods has helped the IBS bit it has interfered with concentration on my RR program and so I need to go back to Step One and forget the elimination diet..Weight loss is not a goal for me..I am at a right weight for my age...Healing of my sugar sensitive body is what matters...thanks for being here .
