I hope the Asacol works for you, too!
If you are curious about diets, you can check out the SCD (Specific Carbohydrate Diet) diet on www.breakingtheviciouscycle.info - it's not easy and by no means a sure thing, but some Crohn's patients swear by it. While it is true that the impact of Crohn's is individual, so some foods might bother others but not yourself, it is highly unlikely that remission can be induced by making up your own diet.
sr5599's diet, for instance, from an SCD standpoint, was doomed to fail because it included rice (no grains are allowed on SCD). On the other hand, some people have seen their symptoms improve just by going gluten-free, so I can see why sr5599 thought it might be worth a try.
