"i&#039;m 19 yrs old going on 20 soon. i&#039;ve been using tri-cyclen lo for 3 months now and i must say that this is the best birth control pill out there! i&#039;ve tried diane before and i was nauseous every morning and i had to stop it before i could even finish a week. with tri-cyclen lo i have not had any bad side effects, except an increase in breast size (happy me!) i wasn&#039;t nauseous from it, didn&#039;t gain any weight, not much difference with my pimples, and most of all i haven&#039;t changed as an individual; no mood swings or change of personality. i&#039;m more than happy with this!
