Birth Control
"I usually use Ocella (been using for 4 years) and switched to Zarah for my vacation because the pharmacy was out, but wow, it triggered huge mood swings and a deep depression the 2nd week in,  By the 3rd week, I was crying every morning and feeling in a slump for hours on end.  It was sporadic, like on and off, sometimes I&#039;d feel fine and then I&#039;d feel horrible again in a few hours.  Yikes."
