bacterial infection
"I took two rounds of this, both were 500mg 3x day for a C Diff infection that occurred after I was on antibiotics for a UTI. The taste is horrible, and it makes everything you eat taste like the pill. The first round was for 10 days, and I experienced mild nausea. The second round I started a week later because the infection came back. I experienced 24/7 nausea that got progressively worse as I neared the end of the cycle. I was prescribed zofran and it barely helped. I was supposed to be on flagyl for 14 days, but I couldn't tolerate it after 10. The nausea was so incredibly awful that I was inducing vomiting to try and stop it, I thought I was going to die at some points I felt so terrible."
