"i can go another 2 years with this. i haven&#039;t gained any weight but my appetite goes back and forth for one day. i can eat once a day or some days i eat four times a day. my sex drive has stayed the same, my hair also broke off in the middle. but since i am a college student and i didn&#039;t want any mishaps that&#039;s why i got it. one thing i can say is that is really does work if you don&#039;t want kids. but the doctor can never tell you how many changes your body can go through.
