bacterial vaginitis
"This is my first experience with BV - the only noticeable symptom was change in odor. 

My doctor prescribed me 500 mg 2x daily of flagyl for 7 days. 

By day 2 the odor went away but I developed bad symptoms from the antibiotics - such as, flushed face and upper chest, insomnia, anxiety, irritability, head ache, ear ache (ringing in ears), dizziness, change in speech and discoloration of urine.
On day 5 I began taking probiotics (2 probiotics to 1 antibiotic ratio) and the symptoms almost completely diminished.
I plan to continue taking the probiotics as a permanent part of my daily regime in order to avoid future infections and/or develop a yeast infection. 
Also, Make sure to eat a solid meal with each pill."
