urinary tract infection
"Just got prescribed this drug yesterday. 2 a day for 3 days. Took my first dose in the morning and the second at night, I fell asleep soon after. A few hours later I was woken up with terrible stomach pain and serious nausea. I ended up vomiting several times. After, it felt a little better but then the pains came right back and nausea persists. Cant sleep, don't think I want to deal with another night of this, hate this medication"
