Is AF causing my excess mucus, asthma, throat clearing?

I have systemic candida, heavy metal toxicity, AF, epstein barr, lyme and parasites. For a couple of years now I have to constantly clear my throat throughout the day. I thought it was a dairy problem so I eliminated all dairy and it didn't make a difference. Candida diet and supps do not make a difference. I have had chest CAT scans and a throat scan, where the ENT stuck a probe down my throat and they were both clear. The throat scan showed slight GERD, but the doctor said it was nothing to be worried about probably not the cause of my issue. I rarely have GERD symptoms. I sleep horribly and recently have started waking up in the middle of night coughing horribly and wheezing. I often have to spit up a huge wad of white or clear mucus when this happens. However, I almost never have a runny nose, sneezing, etc. Stress seems to make my asthma worse as well.

I never had asthma (unless I came down with bronchitis and then it always went away after the bronchitis ended), until the beginning of last year. It seemed to start out of nowhere. Again, the lung CAT scan and tests all came out normal, and the two pulmonologists I saw are at a loss as to what it is. Their dx was, "oh you just have adult onset asthma." WTF? It just didn't made sense to me. I felt it had to be due to one of the conditions I mentioned above.

I have done multiple parasite cleanses and they don't help. Candida diet and supps don't help. My current ND thinks it's being caused by the heavy metal issue I have and that they are probably the cause also for the AF, since metal toxicity will tax the adrenals. She feels if I can chelate the metals, the other issues will improve drastically or even be elimainated. Just wondering if anyone else has these problems and if you've traced them back to AF or heavy metals. Other than what I'm doing, I'm not sure what more to take or try. Currently I'm taking SF722 for the candida, candida diet, shark liver oil for oral chelation (which I plan to rotate to something different soon - any suggestions? Cutler protocol is not an option), a viral supp for the epstein barr, an herbal lyme supp, Vit. D, Vit. C, Zinc and probiotics. Would love to hear from anyone else going through the same thing. Thanks.
