Yep, just soak your fingers for 20 minutes each day in a mixture of vinegar and water. She didn't know the exact ratio of vinegar to water, so I just dolloped some vinegar into a cup of water and soaked.
I was amazed at how fast I could tell this was helping and soon the nails were beginning to clear up. And, as a bonus, my very soft nails are now much stronger.
Don't be afraid to give this a try...the NP assured me that it couldn't hurt, even if there was no yeast infection.
Hope this helps someone out there!!
