I used to, exactly for this reason. I otherwise have a fair deal of aversion to light (the first sunny days of spring are unbearable to me without sunglasses), but I tried to make sure there's plenty of light for me in the morning, as I knew it could have an impact over my circadian rhythm. Unfortunately, all that did was hurt my eyes when I woke up :-).

Nonsense. As an owl I have no problem sleeping when it's light.
