The best advice I can give is to "change". If you always do what you've always done, (i.e. eating the same foods, taking the same drugs, and not getting any better) you'll always get what you've always gotten. No one can predict if an antifungal program will help you get well again. You need to give it a fair shake though, with no cheating, if you decide to try it. But, you should know if its right for you in less than a month.... by Valentine's Day you could be noticing improvement in symptoms, but there are no guarantees. There's no quick fix.
I'd add that natural protocols may not show obvious results quickly, but may still be working. Alternative therapies and lifestyle changes take time, sometimes a lot of time. Also, in my experience, sometimes it's not "this isn't right for me," but rather "this is only one thing that's right for me. I need to find other, complementary therapies, to add to this to address the many causative factors of my IBD."
