I am switching from Orthotricyclen-lo to Yaz mainly because of it's treatment for PMDD. I have been on the pill for years and recently have noticed a change in my emotional state the week before my period. Most prominantly an overwhelming feeling of sadness and lack of concentration/motivation. It's definitely not my personality... However to my surprise at CVS they give me the generic form. this happened to me once before with orthotricylen and it was horrible the way I felt and that generic pill actually got taken off the market. I want to try and help these symptoms not make it worse. Most of women's complaints have been emotional and appetite. I'm scared now! Idk what to do!
