Oh boy. Yes, I have had and am having experience with this. I think you may need to treat this as an overall, rather than a spot-cure. What I mean is, 3-lac may not be enough for you, and it may not be helpful to concentrate on the lungs per se, but rather treat yourself as if you have candida throughout yur body. I don't think there is anything that can target the lungs specifically. Rather the best thing is to do the diet and cleanses. I had it in the lungs, and when I used antifungals, they sure helped but it was rough. When I was at the height of lung detox, I would wake up 2 or 3 times a night gasping for breath, and would have to go into the bathroom (so as not to wake my husband) with my albuterol inhaler (fast-acting asthma rescue inhaler), and sit there for like a half hour, takiing puff after puff, all the while with this white foamy metalic tasting stuff spewing from my lungs as I coughed it out. This went on for about a month and a half. Not fun. Just wanted to warn you in case you find something like this happening to you as you detox. I am not 100% sure I would recommend antifungals now, though, because I wound up pretty toxic from doing them, and now here I am trying to undo all that. It did get lots better though, and now I only get breathing issues if I eat something that doesn't agree with me, and am working on that now as well through liver and colon work. If you can get your hands on an albuterol inhaler, it will at least help symptoms while you are healing.
Cleanse the body and the lungs will naturally follow suit. Bowel, kidney and liver. There are no quick fixes for candida-related issues, unfortunately, and 3-lac helps some but not others.
