"i have been on this almost 4 years, but i do not remember any side effects when i switched over from a pill. i have had acne since i was 12 but now i get maybe one pimple when i&#039;m on my off week. i have not experienced weight gain that i attribute to the patch. my main complaint is my libido does not exist anymore and sometimes i get moody, but i feel like that is normal for women. i personally have had a great experience with it and am thankful that it has been free for me! the application area is itchy sometimes but it&#039;s not a huge inconvenience."
