Boric acid (and a good brand) for Bacterial Vaginosis

I'm hearing alot about Boric Acid suppositories for chronic BV. I am 99% sure it is infact BV that I have (yet again!) but I don't want to keep going to my doctor to get cultured and put on more antibiotics. Does anyone use Boric Acid? I'm prone to yeast infections as well. I eat yogurt, take probiotics, use unscented soap, always a tampon user ( organic brands) but when I got my period this month I used pads so I wouldn't be so sore and thought maybe the blood would "clear up" the BV naturally....didn't work. I haven't been sexually active in a few months but been with the same partner off and on for almost 3 years, def not an STD. What's your take?

Thanks! xx
