Hi I started taking oral lamisil after havina years worth of toenail laser treatment along with using creams and having no luck. The oral lamisil did work but I got some pretty bad side effects. I had a headach for the first month and diarrhea every morning. I then began to loose my taste for sweet. I have a bitter almost sour taste in my mouth that I can not get rid of =[ I called my doctor and I had to stop the medication 20 days early. I hope my taste comes back....
