Nitrofurantoin
"I was a bit scared to take this due to a bad experience years ago but the doctor said its the only anti biotic that will get rid of my current bacteria. First hour I took it, I was nauseous but I kept myself distracted and it's been a few hours and the nauseous has gone. The best thing is to drink a lot of water and eat well even if u don't have the appetite. It's only been a few hours so my symptoms are still there but I'm feeling quite positive that I'll be back to normal in the next couple days due to how strong this anti biotic is"
