I've been on the pill for a total of 25+ years, so I'm not against the pill. It has worked well for me. After my husband had his V, right after the birth of our daughter, I was glad to be able to be off the pill. I was off the pill for five years and felt that I had fewer PMS-type symptoms including emotional swings and blood-sugar swings, and felt great. Unfortunately, we divorced and I discovered in dating that many men over 40 or even 50 have not yet had a V and so went back on the pill. Now, at 50, I use it for both BC and reduction of pre-menopausal symptoms. At least, my OB/GYN assures me that it is "evening out" those types of symptoms. I would love to be able to go off the pill soon, and test that theory.
I really doubt the 60% statement. The reasoning just sounds false. We women in our "natural" state really aren't all emotional wrecks... If a person is suffering from anxiety, there are other treatments for that. Vigorous exercise and a healthy diet are the best cures for anxiety, emotional swings, and premenopause symptoms.
