I started nuvaring after being on the pill for 6yrs and trying ortho evra for a week and ending up in the hospital for nausea. After about a few weeks on the ring I was feeling exhausted all the time, even after 12-14 hrs of sleep. I was moody, in a super depressed mood, and I had no sex drive. I was driving my boyfriend crazy because I was like a different person, and I was miserable. I talked to my doctor about switching again, but she suggested that before I switch I try taking a multivitamin with B complexes and iron because birth control can cause vitamin deficiencies that manifest as all of these awful symptoms. I took her advice AND IT WORKED!!!! Since taking the multivitamin daily, I have had no side effects with the Nuvaring for 4 months, and I feel better than I have in a long time. So before you run to switch to something else TAKE A MULTIVITAMIN! It might save you a whole lot of time, money, and trouble.
