My podiatrist had me on Lamisil by mouth for 3 months. It did go away, but came back. Pentlax (like a nail polish) was next. Didn't do anything. Sporanex was the third and last medication for me. THe fungus did go away, but came back. YUCK, I hate this. HE said he could remove my toenails (both big toes), cauterize it so the nail doesn't grow back, and paint my toe with nail polish to 'fake it' that I have toenails. I don't think so, at least until all other options are spent. I asked him about Vicks, since I had 2 co-workers that used it, and he said that he had heard of that, betadine, and Listerine. There are just so many types of fungus, that what works on one probably will not work on another. I am going to try the vinegar and see what happens. Mine just doesn't look bad, it is very painful at times and right now it is in a painful stage.
Good luck with your trial of home remedies, I will also try tea oil and whatever else I can try. Just remember that it takes almost 8 months or more to grow out. Mine got 'normal' looking, and then the fungus came back.
