Which treatment works the best and fastest for bacterial vaginosis?

Antibiotic: If it was diagnosted as bacterial vaginosis, and you are not allergic to Flagyl then this is the best treatment for you.

Alternatives: Recurrence rates are high even if you get treated and so if this keeps happening: Intravaginal boric acid, a 600 mg capsule once nightly for 14 days may be able to help with your problem. This medication is not FDA-approved for this purpose and must be made by a compounding pharmacy. Boric acid can be fatal if swallowed rather than used intravaginally, so be careful around children.
