i use just a little bit between some toes to keep the fungi from coming back. it takes me a long time to get rid of it once it gets infected so to prevent a new infection is worth a few moments and just a little bit. i use a pair of metal tweezers which when dipped give me just enough to do the job. before i was applying full drops and using my finger to smear it around but it was a big waste and was too much and Mom said it stunk too bad and bothered her. once i switched to more minimal amounts (and also apply it right before bed) she doesn't even smell it at all - by morning the smell is gone. i've tried all sorts of other things as a preventative but nothing seems to work as well.
