Hello, I'm 37 And Think That I May Have ADHD

Hello, I'm 37 and think that I may have ADHD or at least my wife thinks I have it. I have all the classic symptoms (including putting stuff off like seeing a doctor). Is trying to get a prescription for adderall to extreme? I've recently started back to school and have found that it's almost impossible for me to focus for more than a couple minutes. This definitely takes me back to high school years. I always had issues unless I was taking ephedra pill (aka minithins). Please advise.
Thanks
