ohanna, definetly your pcp could help ya. A lot of times if you just call them they will call some nystatin in. From personal experience, if you truely think you have it (white film on tongue causing abnormal tastes) get it treated and be prepared to take the medicine for a while. You usually have to swish this really sugary stuff in your mouth like 3 times a day for several weeks, but DO IT until it all runs out, lol cause I didnt and it SUCKED!! It just comes back even worse.
