"i was on the yaz contraceptive pill for only around 6-8 months, but it was the worst experience. i complained about acne to my doctor and she recommended it, but i did not notice a drastic difference in my breakouts while on the pill. i had been on alesse for 2 years before switching to yaz so i was well aware of some of the side affects to birth control pill use. when i switched to yaz i honestly felt miserable and immediately noticed my sex drive decreased drastically and i had low energy all the time. i had never felt that way while on alesse and i thought perhaps it was only a side effect to just starting the new pill. however, in the entire time i was taking yaz my mood did not change and i felt it best to switch back to alesse."
