"i was on lo-ogesteral and was very happy with it but my doctor stopped carrying it and prescribed me cryselle saying it was the same thing. i&#039;ve been on it for almost 6 months now and am just as happy as i was with lo-ogestral. my period used to be really heavy and lasted a week before i was on birth control. now it lasts 5 days and is pretty light to moderate depending on which day i&#039;m on in my cycle, never heavy. no break through bleeding, no crying jags, no acne, no weight gain. the only thing that happens to me is the first few days of a new pack i get nauseous after taking the pill. but i get nauseous easily."
