I've been on Yaz for a month. I experienced headaches for about 3/4 of the month. I'm supposed to be on my period, according to the pack. I'm not. I've been feeling "blue" all month, even angry. I'm a pretty passive person by nature, so this "blue" thing is not becoming. I've had issues falling asleep at night. I normally crave sweets and soda. Not on Yaz. I crave salty foods. On the bright of things, I haven't experienced bloating or sore boobs at all. I'm drinking more water than normal-so thirsty, might be all the pringles I've inhaled. I don't think this is the pill for me. The headaches are unbearable.
