Bragg vinegar is good however I have found out that the NZ ACV is the best you can get. The quality is beyond what you can find in states. However just so you know ACV alone is not strong enough to get rid of candida. You should incorporate some antifungal and probiotics for faster results. Check cfort10 and probacto probiotics and try it for a month or so.
There is no need to stop your vinegar treatment however as I said it will be a slow process.
Yes you can get yeast infection under your breast, those are the rashes with smell, we have answered that question here on candida questions forum before make sure to check it out here.
I do not know much about the peroxide however I think there is an article on curezone that covers the topic in detail.
