Bacterial Vaginosis Finally Cured

I've had BV for 20 years, but have found that it's got worse over the last 5 years. Balance activ controls it until I next have sex, or have my period, then it inevitably returns with a vengeance. I've tried folic acid, fem dophilus (which worked but is too expensive for me long term)salt water douching etc. 

However, on this occasion, I douched with salt water for 2 nights before bed to kill the bad bacteria and followed with a balance activ pessary to nurture the good, the next 5 nights I only used the pessary. I only wash with plain water, have taken folic acid and vitamins c and d and I'm eating a fage Greek yogurt with honey (from asda) every day as it contains L.Acidophilus probiotics. I've also reduced my sugar intake.
