took this from TotallyADD.com
"In fact, one of the things I’m learning from the course is that most ADDers tend to be next to useless by late afternoon. But we’ll just try and push through it, not getting that a task we could bang off in 30 minutes in the morning, or during our second wind in the evening, can take forever when we’re in our late afternoon brain doze.

Even if you can’t crash out at work, consider scheduling your day to match your energy levels if you can. Which, of course, means understanding and appreciating your energy levels and how much they vary. Coach Linda Walker’s course has us tracking our energy as one of the stepping stones to create a new way of working that dramatically ups our output."

--> ooh! so it seems like I'm not the only one whoe experiences this! that I'm most productive from 10am - 3/4pm, and then I have another spurt around 8pm-1am. haha
