Caffeine and Endometriosis

I gave up carbonated beverages for Lent and found the lack of caffeine greatly reduced my symptoms of Endometriosis. I had minimal pain and it was wonderful. I did a bit of research on the Internet and found that one article stated caffeine intake raises the level of estrogen in your body and also interferes with your liver's ability to cleanse excess estrogen out of the blood stream. The end result of all that estrogen is a negative thing if one has Endometriosis. I have to say the elimination of caffeine is a much easier solution to this problem than surgery. Hopefully the results will continue to be positive over time.
