birth control
"After trying several different birth control options (pill/IUD) this is by far the best one so far ... I've been taking it for a little over 4 years and it is very effective with  minimal side effects - mostly physical symptoms like slight dizziness from time to time and slight discoloration on my face which is easily covered with powder.  Over the course of the last year or two, my periods went from your average 5 to 7 day period to a very nice 3 day, very light period."
