Been on this thing about 10 months, recently have been having blurred vision and 2 days ago passed out, thankfully not while driving with my two children in the car. Decided to see if this was what was causing all these problems. Other side effects have been no sex drive, cranky, anxiety, mood swings, eating all the time, breast tenderness, excessive discharge-usually about a week after inserting a new ring- but to the point of changing panties 2-3 times daily and then before bed, headache, back ache- upper and lower. Obviously I think this may be what is causing all of this due to the many of other women that are experiencing the same things, and also that a few of the serious symptoms are listed on the official web site. I have every form of birth control other than the IUD and of course having my tubes tied. I am at the point that I want to try the IUD, but am tired of all the side effects from every one I have ever tried.
