NuvaRing and sleeping habits

I have been on NuvaRing for about 9 months now. I really love the convenience of it. I have had no complaints until now. About two months ago I was having some issues with insomnia. I tried a prescription sleeping pill (rozerem, I'm not sure how to spell it) for about a week and after I got off of it I was back to my usual sleeping habits. It didn't even cross my mind that it could be the ring. I thought it was just stress from school. I might have been that and not the ring.

I have put on about 15 pounds but again I attribute that to my eating habits, not the ring. However, the past month and a half I have been on a strict diet and meeting with a personal trainer 2-3 times a week. On top of meeting with the trainer I go to the gym for a least an hour everyday. In spite of all this, I gained 3 pounds (on top of the 15). My doctor said it could be my thyroid but I just got the results of my blood test and my thyroid is normal. So I think it must be the ring.

The problem is that I really like the ring and I don’t want to get off it. Has anyone gained weight from the ring but been able to lose it while staying on the ring?
