Apple cider vinegar worked for me within 24 hours. Usually I have 2 weeks of breast pain, however a few days after the monthly pain started out of desperation I took 2 Tb of ACV in the morning. The next day the pain was 90% gone so I continue to take the ACV daily. Be sure to take the Organic Apple Cider Vinegar (unfiltered) because it has more of the curing stuff in it and I found that other brands repeat on me. No one wants to be burping apple cider vinegar all day.
