Birth Control
"I used Yasmin for over 5 years without any issues. It had no impact on my weight and cleared my skin beautifully - however perhaps gave it a tendency to be a little too dry. When I stopped the pill acne returned very quickly. It worked without any issues as birth control. 
In the last months, however, I developed nausea to the pills - for some reason simply the thought of taking them gave me nausea, and at some point when I had to take two at the same time I threw up bile the next morning. I continued to take the pills for a little while, but the nausea was clearly associated with them, not any other factor, so eventually I had to switch to a different brand and composition. I would still recommened; they were OK for a long time."
