quasense instead of levora

I have been taking Levora, instead of Seasonale for monetary reasons, as you all know this generic is way cheaper, however after switching insurance i cannot get Levora dispensed more than one pkt every 30 days, since i take Levora constantly for 3 months this will not work, i am thinking of switching again to quasense has anyone done this? and WHY is it so difficult to get bc dispensed more than one pkt at a time, why cannot anyone understand that some people take bc as medication as a necessity not just to avoid pregnancy.
