I am using Strattera 25 mg, but instead of making me concentrate I am all over like before and not able to concentrate on one thing. I also feel exhausted and over sleep, and as a result I have failed two of my exams using it and tomorrow is my last chance, my doctor refuses to prescribe something else, saying I need to see a psychiatrist to get a prescription for any of my future ADHD, and since I am on Obamacare, and since then I can't get an appointment with any psychiatrist, because they're over booked? Please help!
