I took Yasmin for about 2 years. When I first started taking it I noticed that if I took it at night, like, any time ater about 6, I'd have awful nausea the following morning, and usually end up vomiting. In fact, even if I took it before a nap I'd wake up and feel sick. I figured if I just avoided taking it before I slept I'd be in the clear. I started taking them in the morning and I noticed that about noon time I'd get headaches and I'd feel nauseous. Within the last 3 weeks (it could be the summer heat, but I'm almost positive it's the Yasmin) no matter when I take it I feel awful. Nausea, headache, fever, and consistent vomiting. I finally could not take feeling so sick anymore and today I went to my gyno and she suggested that I take the NuvaRing, because it's not something you ingest, which could prevent the nausea I had with Yasmin.
