"i think yaz is a good birth control pill overall. my doctor switched me to this pill b/c it is one of the lowest doses out there- i needed to go back on bc pills because i suffered from hot flushes as soon as i went off the pill. it took two weeks on yaz to stop the hot flushes (i&#039;m only 42, by the way) and i feel so much better. i do agree, however, that it does make me a little tired and i do have some headaches (during the period week)- but nothing like the monster headaches i got on some other brands. all in all-a good product. i will be on it as long as my doctor allows me to- hopefully to 50."
