Boric acid is not safe. For feminine odor, I'm convinced you should look first the pH. We are not supposed to clean with a soap this part. The diet you want to try seems good, and yes, you're strong enough, but you have to go little step by little step. First, eliminate completely caffeine, try to find a replacement, and try to eat less meat, I don't know how often you eat meat. Vegetable protein powder is not very natural in my opinion. Post what your diet for one day here, and people will help you eat better.
