You should have a good idea in a week or so. Yes, try fruit and veggies on the safe FODMAP list but be careful of the insoluble fiber content as recommended by Heather.
As you probably know sucrose which has equal amounts of glucose and fructose is not a problem. Some people claim that sucrose can be a problem but so far the clinical tests have not shown this to be the case at least when consumed in moderation.
I blend the EFI and FODMAP approaches successfully but you have to pay attention to detail such as insoluble fiber content. Unfortunately, the FODMAP approach leaves issues regarding known IBS triggers such as insoluble fiber, fat, caffeine, etc to the health professional advising the patient.
