I too have tried everything to rid BV.I suffered with BV for 1.5 yrs. I tried multiple rounds of Dr. prescribed gels and creams, with no results. I also all the recommended self treatments on this forum i.e cider, femdolph, tea tree oil, yogurt, acidopholis, vitamin B and Colloidal Silver .It never quite went away until I was treated for a sinus infection, yes sinus infection. I told the Dr. that my past sinus infection was resistant to Antibiotics . He prescribed Amoxicillian Clavulanate Potassium 875 mg for ten days twice daily. I had been making sure that no semen entered my system and was taking acidoph....but i was doing those things in the past with no results. So the only thing I can say is the amoxicillian worked. I am so HAPPY. I have been free and clear for 4 months....
