Nitrofurantoin
"I'm on it right now, it's my 3rd day out of 5 on it and even though it got rid of my UTI right away I have been feeling sick. I feel super nauseous at the moment and I can't get any sleep because I feel like I'm going to vomit, I feel bloated and have a tiny headache. I think this medication is way to strong for me, I would prefer taking something that gives me less side affects. Worst antibiotic I've ever taken."
