I have gone nomail for a short while, so would ask you to email me directly if you have any information I could relay to a client, who has a history of endometriosis, but has enjoyed a year of breastfeeding and no periods. She would like to know what women experienced before they resumed their periods. She is feeling very crampy. What is your feeling about Oil of Evening Primose to relieve these symptoms? Thanks for any information. Kathy Bodden, RN, BScN, IBCLC, Toronto.
