"is extremely nauseous, loss of appiette and bad heartburn. i feel sick whenever i eat and have vomitted. has had severe heartburn; difficulty breathing and very uncomfortable(reoccurring but not always severe). has had mood swings - happy to sad and vice versa. have cried and felt emotional. sex drive not effected like others have said in their reviews. i do get the occasional stomach cramping. i have a very busy life so i love love the one time application, set my date for removal and forget about it.  im trying to look past the extreme nausea---but if i did not have that i wouldve been happy with nuvaring."
