"I&#039;ve taken Yaz for 3 and a half years, but when I first started it was a nightmare! I felt sick all the time with no appetite and the first period I had on Yaz was even worse! I was way more moody than I was off the pill and would just start crying for no reason. It got better and my periods were lighter, but like most after that 3 year mark I started feeling anxious and depressed. I&#039;m getting switched off of it now because of it. It&#039;s great for short term."
