No reason not to take both the commercial and homemade solutions. I would take anywhere from 2 to 8 ounces daily depending upon the severity of the infection and then once the infection was mostly conquered cut back to a couple of ounces a day and eventually taper off to just a tablespoon or two before stopping. That can get a bit pricey - though one of the companies has a buy one, get one free regular special for first time buyers and last time I looked they had a 50% off sale going on, either of which could help a lot with the cost. Thus you might wish to cut those amounts in half after the first couple of days and augment with more of the homemade. So long as the silver solution is properly made, I think you can hardly take too much over the very short term.
