How strict you need to be all depends on how early you diagnose. Crapshot managed to heal while eating sugar.... as for myself I was in bed with chronic fatigue and rhumatism when I finally found out.
Twenty years ago I had come to realize I was intolerant (allergic to sugar) but candida was not well known back then. So my case is a long story. I have been on the strict diet (one cheat day a week) for a little over a year. And I am doing so good now, I think that within 3 months candida will be history.
Crapshot took about just as long to heal his mild candida, while eating sugar.
