Parasite-related skin sensations persist despite lifestyle changes

I use to use MMS a year or so ago. My family and I have been plagued with parasites in our skin. Crawling sensations insistant in our bodies. I didn’t stay with it and it did not seem to work for me. I don’t know if its because of my weight or what. At the time I didn’t really understand how to use the product. I have been overweight for smoe time so I don’t know exactly how much is needed for my size. I have been diagnosed with elevated liver and I don’t drink. My family and myself have started eating healthier for over a year (had good weightloss) however we can’t shake these things. We feel them all the time. Even in our home, car, or wherever. Can someone give me some advice?
