I think I have adult A.D.D.- advice sought from anyone with this

[metsm1234]

During high school I had no problem maintaining concentration throughout classes and exams. I noticed a change towards the end of my college career but it only led to a small decrease in grades. Now at work, I find it very difficult to concentrate on completing my work. I lose focus and think about other things. The next thing I know a half hour or more passed.

I am thinking about seeing a doctor for this because I am starting law school soon. Have any of you developed this problem later in life? I am 24 years old. I do not think I have the full blown disorder but I find that my ability to concentrate is affecting my work.

Thanks
