Hey there. I have also posted a topic about my fecal odour problem. I have outlined what it may be and how I felt better while on candida diet but not 100percent. I think that your problem is an internal problem most likey your digestive tract. You have suffered a lot more years than me, I suggest you start start veggie juicing for a week and try blue herbs colon cleanse. I'm certain you'll feel a hell of a lot better maybe it'll cure you. My problem may be different than yours
