asperger & adhd & adderal

Hello, I have a son who is 8 years old, He has been diagnosed with Aspergers and ADHD. Before giving birth to him I had complications during pregnancy, I had gestational diabetes, and placenta previa. Since he was about 3 or so his behavior seem to be getting worse and worse. Since he started school he had problems getting along with other children. He always wants to win at everything, and if he lost to a game or something he would have a big fit and possibly hit some other child or teacher. He has bad outburst using curse words etc. He hits himself in the face sometimes if he did something wrong and he knows it. He always wants to be first in line. At school he don't like to read or write. He spaces out. His language is really slow and he cannot speak a whole sentence correctly. He loves computers, he knows how to make colored cursers etc. I don't even know he he does that. He loves video games. He loves math and is very good at it. He loves mc donalds, popcorn, grilled cheese sandwiches, candy, pizza, he loved drinking milk at some point. Not anymore. The only vegetable I can get him to eat is fresh snow pea pods and carrots. The teacher seems to fear him. He often says I'm going to kill you when he is angry. Must be from video games. He gets a thrill of some other child getting in trouble. I never thought he had feels about anything until I took him to see the movie invisible he cried at the end, I was relieved that he does care and has feelings about death etc. Anyways because of his behavior he goes to half a day at school. I recently took him to a doctor and he put my son on adderal which I refuse to give him because of bad side effects. He also has to attend impulse classes for his behavior. I still haven't giving up hope. Can someone help me on what to give him?
