I just started on Lamisil this week. My manicurist recommended tea tree oil but the smell of it made me sick. I tried it at night and had to get up and wash my feet because of the smell. Doctor said you need to treat for months and months because you have to wait for the whole nail to grow out. My doctor said it is becoming really common from some of the pedicure places not being as sterile as they should be. I have switched to a place that uses disposable foot soak tubs and has a sterilizer for her impliments. Hopefully it will clear up.
