I am sorry that you have been having so many problems with Bacterial Vaginosis.
Let me first explain what BV is, so that we can help you with the treatment.
BV is a polymicrobial clinical syndrome resulting from replacement of the normal hydrogen peroxide producing Lactobacillus sp. in the vagina with high concentrations of anaerobic bacteria.
If the oral antibiotic prescribed caused a lot of sickness, it is best to ask for a local vaginal gel (Metronidazole gel OR Clindamycin cream)
Women should be advised to refrain from sexual activity or use condoms consistently and correctly during the treatment regimen. Douching might increase the risk for relapse, and no data support the use of douching for treatment or relief of symptoms.
A self-help approach is lactobacillus colonization therapy — which attempts to boost the number of good bacteria in your vagina and re-establish a balanced vaginal environment — possibly accomplished by eating certain types of yogurt or other foods containing lactobacilli. While current research shows there may be some benefit to probiotic therapy, more research is needed on the subject.
You can certainly try lactobacillus preparations available Over the Counter for oral use OR even vaginal use, as they do not have any side-effects, and may be helpful in some people.
While chances of recurrence are high with BV, a proper long term treatment regimen with changes in diet and use of natural probiotics may help you feel better sooner :)
