I have been taking Adderall for several years now. I have to have it to be able to concentrate at work. It works well with helping me concentrate. I have a very difficult time sleeping at night. I toss and turn all night. I have tried melatonin, Valerian Root, Benadryl, and Trazadone. None of them help. Is there anything else someone can suggest besides a narcotic to help me sleep/?
