Mercury can cause all kinds of problems, including the ones you described. That is almost certainly the reason why you feel bad now.
Here is my story in a nutshell...
I started to feel sick decades ago. I often had a stuffy nose, headaches, temperature intolerance, Raynaud's Phenomenon, Eczema, chronic fatigue, an irritable bowel, Fibromyalgia-like symptoms, emotional difficulties, forgetfulness and many other problems.
I went to doctor after doctor, and they couldn't really help me. Sometimes a doctor gave me medicine to help with a symptom; sometimes it worked, sometimes it didn't and sometimes it made my problem worse. One doctor said he thought I have Systemic Lupus while another thought I was suffering from depression, even though I wasn't sad. I was mostly frustrated because of my health problems (
Depression is, however, an often described symptom of what I really have).
Finally, I started doing my own research. I found Celiac Disease, and I tried a gluten-free diet. It helped, but only for a few months. Then many of my symptoms returned as bad or worse than before.
I discovered yeast and tried an anti-yeast diet, yeast killers and probiotics (The most effective yeast killer I've used is x-virgin coconut oil). I followed the treatment for more than a year. I felt better, but every time I broke the diet, the symptoms returned with a vengeance. I was also becoming intolerant to more and more foods (this was before I understood the need for rotating the foods on the diet). I was losing hope.
Then, the breakthrough. I discovered mercury. I discovered that silver fillings are 50-60% mercury, and the mercury is constantly flaking off into a person's body. This, of course, can cause many problems, including yeast overgrowth.
I was skeptical, but I took an expensive leap of faith and had my fillings replaced and began using supplements to chelate the mercury from my body. It took time, but after 6 months I was feeling better. I could break my diet and my reactions were relatively mild. After 12 months of cleansings, I could feel even more improvement.
Now, I've been cleaning for a few years. Many of my symptoms are gone or much less than before. Recently I went to Cambodia for 2 weeks. I broke my diet every day for 2 weeks. That would have knocked me out before I began the anti-mercury cleansings, but now I feel some discomfort, but it's fairly mild. I'm not ready to leave the diet completely, but my condition has improved drastically. My only regret is not figuring this out sooner.
My message to anyone who reads this is that yeast and/or mercury is very easy to confuse with other health problems (Celiac Disease, Depression, Lupus, IBS, Fibromyalgia, etc.). There may be more people like me out there. I suggest that you do your own research and find out more about this, especially if you're having trouble finding relief.
Mercury from silver fillings is probably the most common cause, but there are others. If you have silver fillings please consider getting those poisonous things out of your body and chelating the mercury out (replace the fillings before you chelate. Not doing so can make you very sick). I think it will help you the way it helped me.
Thanks for reading. I hope you find it helpful.
