Giardiasis
"I&#039;ve had this for 4 years.  I&#039;ve seen many doctors and have lived very miserably and confused.  My mother ignored me and kept calling me a hypochondriac but I wanted answers.  Last week they figured it out.  I&#039;m on 500mg Metronidazole 2x daily for 7 days.  Today is the 7th day.  I have never in my life been so terrified of being unhealthy forever.  I want to heal.  On Tuesday, they will be testing my stool to see if I have rid myself of this infection.  If I do not get rid of this stupid bug, I will be soo disappointed.  And the metronidazole feels highly toxic.  My tongue is yellow from all of the yeast in my body from my gut flora being annihilated.  Someone comfort me. "
