Cannot stop peeing!

I read online that Lasix abuse helps lose weight. So i took 1, which was prescribed to my dog for his lungs, this morning. I now cannot stop peeing for 5 mins. While waiting for cabs earlier on, i had to rush to the nearest loo to pee, thrice. Ended up i was late for work. And during the 10 mins journey to reach the office, i almost cried in pain. I HAD to pee! And it coming now.... gotta go!
