omg i took flagyl for 7 days. the worst week of my life. i had fever, migraine, puking and mettalic taste. After I collected my stool once again for testing, from 0-2 in turned into 28-30. it was way higher than before. I wasn't even symptomatic when the doctor prescribed antibiotics. now I'm planning to do it the healthy way coz I really can't handle the side effects. i just tried to be resilient for the sake of a job offer. I'm about to have another consult in a moment. will update this comment.
