Very good suggestions so far! Although I have not been formally diagnosed, I believe I too have ADD and it has affected my work as well (documentation is one of the hardest parts for me too because I am least interested in this part and it can be lengthy....I am an occupational therapist, so I too have quite a bit of this at the end of the day). Aside from taking breaks and drinking coffee, I also found that my mind is less exhausted at the beginning of the day, so if I am too mentally drained by the end of the day, I go home, and return to work early the next day to give myself time to catch up.

Also, when I start new jobs (which is often), I always try to brief my boss about my condition, and explain that when she is talking with me, I absorb more if information is in short bursts (I tend to get go somewhere else mentally when a person speaks for long periods and fill in my "uh huhs" and "ok's" as needed......only problem is, after I walk away, I realize I missed half of the conversation).

Another problem I have encountered with work, is I tend to burn out easier than most. When I first start a job, everything is great because everything is new, challenging, and there is much to be learned. However, once I get past the "new" stage, I tend to get bored easier on the job and things such as documentation slip behind. Although most people may not have this option, I have adapted to this problem by performing short term jobs with fewer commitments (travel, local contracts, multiple PRN positions). By the time I get bored at my place of employment, it's time to go!

I do agree with the others in saying it would probably be wise to request reasonable accommodations to help improve job performance. On top of that, if you do continue to experience job loss, you have proper documentation on file and have followed the necessary steps on your end to ensure your rights in accordance with ADA laws are maintained, and have more ability to act accordingly if your rights are violated.
