"I have a YEAST infection AGAIN. I get them pretty often. Is this a sure sign candida is taking over my intestines?"
YES! I would say so. Once candida makes a home in your body, it's very tough to get rid of. I don't think just probiotoics will do the trick; they didn't for me.
Try the olive leaf...it's cheap and very powerful...I felt significant "die-off" symptoms (achey joints, etc), so it must have had a lot of work to do!
I can't say I'm off Sugar entirely - it's been quite a struggle- but I'm sure that's how to get the best results and stop encouraging candida growth. I haven't given up fruit and use agave to sweeten, which I like MUCH better than stevia. I thought stevia has a chemical taste.
