"like many others, this pill causes me extreme breast tenderness.  my nipples get so sore that even the touch of a cotton t-shirt is excruciating at times.  even more annoying is that you absolutely have to take this pill at the exact same time every day.  i get up for work at 5 or 6 every day and take the pill right when i get out of bed.  but on the weekends, if i sleep until 7 and take the pill when i wake up, i start my period all over again!  i understand that every birth control pill is most effective when it is taken at the same time every day, but a 2 hour difference is minimal and doesn&#039;t affect other pills.  other than that, i had not other side effects, but these are pretty annoying...especially the timing issue."
