I am 25 and I take 10mg of adderall everyday for adult add. It makes me cranky, parched (dry mouth) and I'm never hungry. Part of the agitation comes from suddenly feeling focused, so focused that anything that is not focused like you is irritating. 50mg seems like a lot for such a small girl. I have found that if I eat right before I take it and I force myself to eat throughout the day (especially something like bread) it helps to make me less cranky. It's not easy to do but it will help. Also, drink LOTS of water! Prolonged dry mouth can cause cavities in your teeth. Maybe talk to your Dr. and parents about putting you on something a little less strong.
But I wouldn't recommend ditching the drug completely. I have had ADD my whole life but didn't start taking adderall until last year. I was blown away by what I had been missing! I had ALWAYS struggled in school but if I could go back and do it all again knowing what I know now I would do so much better.
