BV AND Thrush........................…

I posted previously describing symptoms of thrush. its been a week now and i've tried the canesten pessary, the oral capsule and the cream. I finally went to the nurse who suggested i may have bacterial vaginosis as a secondary infection. She prescribed 2 400g metrocanizole tablets per day. Have any of you had success with this treatment? I couldn't bear to take these for a week (which make me nauseous) only to have no improvement.
