I wonder if they have changed the ingredients in the NR over the past year. I was reading a few other responses where things began to happen after long term use. I recently began the NR, about 2 weeks ago and I have already experienced the night sweats and frequent hot flashes throughout the day,as well as psychological effects. It could also be possible that your body is going through it's own hormonal changes, as these shifts happen throughout a womans lifetime. Maybe now, you are producing more or less of a certain hormone that reacts adversely to the hormones in place due to the NR. That could be the reason for each woman's different experiences with the ring. Dr.'s sometimes don't look at all of the possibilities, which is kind of scary. Women know their bodies....most women, and I listen to mine, listen to yours.
