I've woken up early for months now for the same reason, and it works great. The problem is, it somewhat screws up my social life.
I wonder if there's things you could pre-emptively do at work to not feel tired afterwards. Maybe cut down caffeine intake and only use it just before leaving work? Or take a nap at work.
This is the public group instrumental rationality diary for November 16-30 (that I've now fished out of my drafts folder, *cough*.)
The poll earlier this month seems to be sufficiently in favor of maintaining the current schedule that extra votes are unlikely to change things much, but if you'd really like to register your opinion, you are welcome to do so here.
Thanks to cata for starting the Group Rationality Diary posts, and to commenters for participating.
Immediate past diary: November 1-15
