"I was accidentally put on Yaz when I was supposed to be on Yasmin back in July 2008. I just decided to stick it out and see if there was a difference. The 10 microgram difference in dosage made a HUGE difference. (Yasmin 30 microgram, Yaz 20 microgram) From July 2008 to January 2009, (the time I was on Yaz) it was completely miserable. I had constant nausea, would feel sick eating anything with lactose, had mood swings that almost cost me my relationship, unbearable headaches and at times I had sharp shooting back pain. I felt completely unmotivated and it had a negative effect on my school life. Once I switched back to the 30 microgram dosage, (Ocella) the side effects decreased dramatically."
