Terbinafine
"Been taking terbinafine for 5 of my 12 weeks.  Starting to see a little difference in toenails.  Athlete's foot is gone!  However, I have a sore throat.  I am a little more tired than usual.  The worst side effect is the complete loss of taste!  I hate it. I have lost a couple of pounds because of not eating as much.  I would advise that if you lose your sense of taste, to make sure to drink plenty of water and avoid any really dry food - they will just taste/feel like cardboard in your mouth."
