I have been on Sprintec for 2 months and i loved it never got sick never had any problems but my pharmacy switched it over to estarylla they never asked or told me i thought they would have at least have to ask my doctor.. Anyway i have only been taking estarylla for a couple days but i have had the most terrible headaches since i started taking it and i have been nauseated really bad and my acne is terrible i never had any problems with these with sprintec the pharmacist said they were the same thing just different packaging but i dont think so someone please help!!!! Or am I just going crazy????
