Bacterial Vaginosis (BV) remedy? HELP?!?

Ive been struggling with bacterial vaginosis for like a month now! I dont have any health insurance and yesterday I went to a free health clinic to see if I could get a prescription for metro gel! well after waiting for 2 hours the doctor came and saw me.. he asked me what the problem is I told him I believed I had BV and he prescribled me Metronindazole (without even checking me out)

Now Ive had BV before and I was told to either do a gel for 7 days or take a pill for 7 days.. The doctor told me to take the Metronidazole (500mg) ONCE..just ONE pill!

Well the prescription came with 4 and the one pill didnt do anything! so im going to take the rest (one every 12 hours)

If this doesnt work I cant go back to the clinic because each follow up visit is 100 bucks that I just dont have. Im hoping someone on here can give me some home remedies.. Ive heard of douching with hydrogen peroxide but I dont want to do that..but what about hydrogen peroxide in my bath water?? if so how much??

please help me!
