Hi Icebee,
I have been on yasmin for about 3 years now, and I have not felt nausea, or any other side effects, besides the occasional one during menstration. However, IT IS VERY common to feel like that when you start most BCP's. Yasmin is a very powerful pill though, so if you continue to feel sick you should consider switching to a pill with a lower dose of hormones. As for clearing up acne, is has done on decent job; I still have had acne but not as severe, and when I decided to go off Yasmin, my face REALLY brokeout so it does work to fight acne. Now, I actually work for a skincare company and I have been told from several of my co-workers that yasmin is the best pill on the market, so stick with it if you can!
