I am new here. Thank you for the add. I was told that I have fungus on one toe but that it spread to most of the other toenails. I was prescribed terbinafine but I could not tolerate it. I went for a second opinion and bought the very expensive Tolcylen. Has anyone had success with it? I put it on all my toenails but of course I'm concerned that I'm spreading the fungus further.
