Vaginal Yeast Infection
"I had what felt like a moderate yeast infection. I was given Terazole 3 at first but had the most horrible allergic reaction that made my yeast infection symptoms increase 100x. I have never felt misery like that in my LIFE, it felt like my insides and outsides were trying to kill me. 
I was switched to the single dose of 150mg Diflucan and my symptoms improved by half within 24 hours and only got better from there. It took about a week for all discomfort (including the occasional minor itch) to completely disappear."
