I'm most alert in the late morning or late evening.
However, for me, alertness is almost negatively correlated with actually getting things done --- unless I'm working on the "1% inspiration" parts, I have major trouble staying on task.
For the "99% perspiration" that makes up any project, the early morning is often better. I'm not so tired as to fall back asleep, but I also feel as dull as a butter knife -- which actually helps with plowing through the necessary tasks that don't necessarily inspire excitement.
