Ladies, I dealt with BV for years. I took all the medication over and over again and heard all of the suggested precautions: no baths, no tight clothes, no thongs, etc. I did all of that and nothing worked. The doctor suggested that I go on a maintenance Antibiotic indefinitely. No thanks.
About a year ago, I started doing home remedies. I started with the peroxide as a douche/wash and this only masked the infection. I tried the garlic, tea tree, apple cider vinegar, you name it i tried it.
This is most definitely a nutritional thing. Here is the only thing that worked for me. Accuflora probiotics DAILY. I took about 5 a day for the first week. Plain unsweetened yogurt every single day. EVERYDAY. Green vegetables. EVERY DAY. Folic acid supplements. This is not going to work overnight. Give it a few weeks. I promise you this works.
When my diet gets poor or when I forget my supplements, the infection will start to come back. I also think that lemon juice may hurt more than help this infection. I had been drinking a lot of lemon juice and noticed that my infection was starting to come back. Coincedence? I don't know. I am going to keep an eye on it.
Also, for immediate help with hiding the smell, clean yourself with Balneol perineal cleanser. This will mask the smell. Try it!
