"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."
