I'm so glad to have found this website! i have been on NuvaRing for a year i think, and about half a year ago started to feel weird: all i wanted to do was sleep, or sit on the couch covered in blankets (was feeling cold all the time), not go out to exercise and eat eat eat! i am an extremely positive person, i love to go running and doing outdoor things, am almost never cold and never need more than 8hrs of sleep. a friend told me it might be the Ring, so i stopped with it for 2 months. immediately felt better and became my happy self again. just a week ago i decided to put it in again, because of a new boyfriend and leftover rings, not wanting to get pregnant. I've been on it for only half a week, but after reading all this took it out again immediately. i am not crazy, it really is the ring thats causing it all. i had a big fight with the boyfriend this morning, and it was only after i talked to a friend that i realized it was the ring. i understand that for some ppl it might work really well, but for now, I'm just gonna have another massive dinner and wait for the side effects to go again. good luck everyone, listen to your own body and talk to friends who know you, they'll be able to tell you somethings different.
