clostridial infection
"I was on this medication twice a day for ten days for C. diff infection. I just finished my last round today and wanted to give a review. 
I have experienced nearly every side effect possible. Terrible nausea, dizziness, tingling sensations in my legs, and insomnia. They were the worst the first few days on the medicine, however, all of my C. diff symptoms have done away and I feel much better. 
I'm giving it a 9 since it was effective, but the side effects were bad. 
It is a tough medicine to take, but I do recommend it as the side effects will go away and it will relieve the symptoms of C. diff."
