"this is the first and last time i ever use this birth control. i chose it because of the comodity of only replacing it once a week but i have to say that as soon as i applied the patch i started feeling anxiety, my arm felt sore where the patch was, i could not fall asleep. it was horrible, i decided to rip it off and guess what it took me less than 10 minutes to fall asleep. whether it&#039;s effective or not i can&#039;t say i only used it for a day"
