I put the NUVARING in yesterday morning. By last night, I was feeling not quite myself--my appetite was gone. I didn't sleep a wink last night and this morning, I woke up so nauseated and so sick, that I couldn't go to work (that cost me $100). I had a sore throat, headache, stomach pains, and extreme nausea. Once I pulled through the worst of it and could sit in a chair in front of my computer, I started searching on line and found this forum. After reading, I pulled the darn thing out (that cost me another $60 since my insurance didn't cover it). I fell asleep for a couple of hours and now I feel much better. The nausea is gone, the headache is gone, the shaking and sweating are gone. I still feel a little worn out but it's been a rough morning!
