"mononessa has been my birth control for 2 years now. i have never had a single problem with these particular pills. i have had no mood swings, weight loss/gain, nausea, etc. i feel the same exact way as i did before taking birth control... just protected! i am very strict on myself with taking it at the same time every night. i set an alarm on my phone and take it at the same time every night. i have never had any problems with the pill. i really recommend trying to see if it works the same way as it has for me."
