Onychomycosis, Toenail
"I am on my third month of taking Lamisil.  I had no side effects for the first two months and now I have frequent diarrhea (every day).  I just don&#039;t understand why I am now getting the side effects.  I am always thirsty, feel dehydrated and have a bad taste in my mouth most of the time.  Slight headaches here and there.  Did anyone else have side effects that came after two months?  Luckily this should be my last refill of this medication.  I haven&#039;t noticed any positive changes in my middle infected toenail, but a friend who took the medication advised me that it could take six months or longer for a new nail to grow in.  Staying positive."
