vaginal yeast infection
"Woke up next morning from first dose not feeling the greatest. Within a short period of time I was vomiting, had the chills, worst aching all over that I have ever had. Lasted over 3 hours. Finally...slept most of it off after 6 or so hours of sleep. Woke dizzy and had a headache that lasted through the next day. Really thought I was dying but too sick to move."
