"i have been taking prozac (fluoxetine) for about a month now. i&#039;m 15 and i am taking it for anxiety disorder and depression. so far it has been working. i have not been at all depressed for a while. it took about a week and a half for it to start making a difference. i noticed that i&#039;m more calm when it comes to stress. i like it. i&#039;m taking 10mg at the moment. the only complaint i have about it, is that i have noticed an increase in appetite, which i hate."
