Okay, So I have been diagnosed with ADHD since 2nd grade. (I am in 10th grade now) I stopped taking it in like 7th grade because I thought I didn't need it, but I am finding it a lot harder to focus now, and am going back to the doctor to get more meds. I have tried stretera, which made me feel sick ALL the time, and daytranna, which irritated my skin. Anyway I am a 15 year old girl. 5'5" and 135 lbs, anyway, what medication do you think he will prescribe, thanks.
