"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."
