Urinary Tract Infection
"I too suffer from frequent urinary tract infections. I am now on round 2 of this medicine.  My last pill was 4 days ago and I had a re-occurance of my irritable bladder symptoms the next day.  My doctor gave me 7 more days. I did feel sick in the beginning when I would take them with nausea and I felt like I had the flu. Headache is common too. I feel flushed as soon as they kick in usually. I do always take them with food and so far I am just not impressed. I am keeping my fingers crossed."
