NuvaRing and basicly

I went on nuvaring in April 2005, I am a very active person, workout two hours a day and enjoyed my life very much. In September all engery levels dropped, all interest dropped I was angry all the time, cold and did not want to do anything but lie in the bed whcih is not easy with a one year and a five year old. Went to the doctor last week with all the symtons and he basicly said it was all in my mind and the nuvaring could not do this. The pharmacy companies should do more research before putting this on the market and doctors should not prescribe it without making sure
