urinary tract infection
"Everyone reacts to drugs in different ways however I will never again take bactrim. I started feeling tired and got a bad headache the second day after taking it. That same night was even worse... I felt nauseous, my head hurt even worse, and all I could do was cry. I felt like I wasn't even in my own body. The medicine definitely messed with my head. It was the worst feeling ever. Now I know to never take bactrim or any other sulfur drugs!"
