"i have been on yaz almost a month. the reason why i picked, and like this medication is because it doesn&#039;t give me mood swings, which every other birth control always causes. my complaints are that i have seen random acne pop up here and there on my face, and a little breakthrough bleeding. i also have cravings, and get super nauseous at the thought of certain foods. i am definitely a picky eater now, and would prefer not to eat, than eat something that turns my stomach (which seems to be a lot of things lately) my breasts are more &quot;perky&quot;, and all my milk from my son has dried up fairly quickly. i do get dizzy, it&#039;s happened twice only. i also feel a little spacey, but it&#039;s getting better. not sure about weight gain, if any."
