I should have updated. Ok, fist off, they are very high quality. Secondly, I also take another medication for my ulcers. So, just to make sure my suspicions were correct, I decided to stop taking them. The UTI has gone away and I am now taking my multi-vitiman again. I know it was an UTI because I have had them before when I got sick once. So I was aware of the symptoms. Thanks. :)
