"I was on Yaz for a couple yrs, then my gyn suggested I begin taking Gianvi which is generic for Yaz.  It was cheaper &amp; figured I would try it.  Big mistake.  I noticed I started to have horrible mood swings..I would be laughing one minute then angry or uspet/crying the next..for the smallest reasons.  I am also hungry all the time!  I&#039;ve gained 5 lbs, no big deal..I honestly don&#039;t know how I haven&#039;t gained more.. I crave food even if I&#039;ve just ate.  I also noticed my vision is blurry.  I was wondering if my contacts were just dirty &amp; needed changed...but I still notice it. My sex drive has also decreased a lot which was never the case on Yaz.  My boyfriend &amp; I have decided going back to Yaz is probably the best decision! For both our sakes!"
