"i was on yaz for about a year and decided to try the generic because of the cost of yaz (about $60 a month, but had to pay $180 upfront for 90 day prescriptions). they gave me loryna and i&#039;ve only been on it for 3 weeks and i&#039;m feeling miserable! i have extreme fatigue, irritability, moodiness and a little breast pain. i know they say to give the pill 2-3 months to work but i don&#039;t know if i can handle another 2 more months of these emotions. i&#039;ve tried a lot of generic bc pills in the last 5 years since they discontinued the one i was on and i&#039;ve had problems on all of them. sometimes those generic &quot;inactive&quot; or &quot;filler&quot; ingredients really do have an impact, be careful and wary of your side effects!! i&#039;m going back on the brand yaz."
