Yep, diet affected my pain as well. After my lap I cut out caffeine and sugar and it helped immensely.

Another good book to read is "Endometriosis and Other Pelvic Pain" by Dr Susan Evans. It's really good and gives lots of good advice about managing endo through diet, etc.

Skipping periods with the pill didn't do much for me. It wasn't natural, the pain was a hundred times worse when I finally let my body have a period. It was almost my body was trying to force it but I was resisting.
