i am actually taking a 'cure it from home' approach, since i really don't want to take lamasil or anything like it if at all possible.
i'm using a couple cups of vinegar added to about the same or a little more hot water and i soak for 20-30 minutes at least once, sometimes 2 times a day. when i'm not soaking my feet/nails, i apply by spraying all over my nails straight up vinegar, then i apply tea tree oil to the nails all over and under.
i AM seeing results! although it is taking a while (i've been doing this for a month), i can see new, clear nail growth at the base of my nails!! i have had this issue since before my 9 year old son was born, and i am SO happy to be getting results, even if it does seem to take forever.
hope this helps!
