"I took Lamisil for about 6 weeks. My toenails started looking better right away. I could see the new clear nail pretty quick. I started having bad heartburn and stomach pains. Everything starting smelling and tasting the same and terrible. I lost 10 pounds and could barely keep food down for 3 weeks. It has been about 6 weeks since I stopped taking it and I am still having loss of taste and stomach acid problems. Liver tests came out normal. I have never been allergic to a medicine but unfortunately I was in the 1% of people that got the side effects from this medicine."
