where do i start.... I'm 16 and my doctor is having me take this because i get ovarian cysts ALL the time. i started about 3 months ago and i hate it. before i started taking it i was a very very bubbly person who did really well in school. now that i am taking it i have changed. my math grade went from a 90 to a 50 and i got very frustrated when i was trying to make up my work and i would end up either walking out of study hall i had with her or i would cry. i had no ambition to go to school and while was there all i wanted to do was sleep. i started fighting with my boy friend a lot more and everything seemed to either make me mad or upset quite easily. it is very annoying. and with my family history of cancer i have to be careful of what i take. i would almost rather deal with the pain i got from my cysts then to deal with this.
