Adderall XR and minute assignment

Mydaughter is 8 and in second grade. She has been diagnosed with adhd. We have been taking adderall xr for about a month and a half. While the school day goes well for her, the afternoons and ugly for us. She is very agitated, cries for nothing and irratic for about 1-2 hours. We also have a hard time getting her to sleep. Her doctor prescribed Lunesta 1 mg, but it takes a long time for her to go to sleep. We start around 9:00 or10:00 and it takes a good 1 1/2 hours to get her to go to sleep. She does not sleep thru the night either and has never been a good sleeper. ALong with this add she also has hydrocephalus. While this works great for her attention problem in school, it is very exhausting for me in knowing how to handle her moods, outbursts and the sleep issues. Any advice on either? Thank you
