urinary tract infection
"I was prescribed Microbid for a UTI that I had for about 2 weeks. I took 2 pills so far 100mg each. I have stomach issues so I took mine with vanilla yogurt and had no nausea or vomiting. I highly suggest yogurt when taking antibiotics. It works like a charm. I have had no bad issues or side effects. I already feel better after 2 pills. 
Give the medication a chance it's working to kill bad bacteria which can make anyone feel yucky. Good luck!!!"
