Folic Acid & BV

[talks-to-walls.livejournal.com]

Well I think my BV came back, AGAIN.  I really don't want to go back to my doctor and pay all this money if I can take care of it myself.
I've heard about taking Folic acid and vitamin B(?), would this cure my BV?
Can this also be used on a regular basis to help it from coming back?
How many milligrams should I take? 
Will this effect HBC?

Thank you for your time!
