Can you get rid of hypoglycemia for good if you just follow a very strict diet for a certain amount of time?

I am 27, and I have had reactive hypoglycemia since I was 18. I have learned how to control it, and I pretty much never have candy, and rarely have desserts. I drink every once in awhile, but make sure i balance it with protein. If I were to quit eating white flour, sugar, alcohol, etc., COMPLETELY for awhile, would that cure it indefinetly?
