Specifically, my doctor diagnosed me with BV and prescribed some very expensive vaginal cream, which I bought and used. It worked, but within a few weeks the BV was back. So I tried an Miracle-Mineral-Supplement douche. I activated 30 drops with citric acid and added that to a large douche bag of water. I had to do it several times over a week, but the BV went away. I think it came back two more times, and each time I would treat it with the Miracle-Mineral-Supplement douche. And now it has been about 6 months since I last had BV.
I just did my douching standing up in the shower. No attempt to hold it inside. And I was careful to follow the MMS douche with a fresh water douche to make sure nothing would get irritated in there.
