Nitrofurantoin
"I was diagnosed with a UTI about 2 weeks ago and was put on this medicine for 7 days. The burning and urgency symptoms went away, but I still feel "uncomfortable". I called my doctor and she refilled my prescription, so after another 7 days if I'm not better, I will go back in to see what's going on. 

I take the pill once in the morning and once at night (with food). 

Symptoms: I've taken this medication before and maybe it's just me, but I feel like my mood changes when I'm on it. I feel super emotional and just get super upset and even feel angry at times. So ready to be off of it in a few days..."
