Springtime sunshine problems?

Now that it's spring, there's a lot of alternating days between bright sunshine and rainy clouds.

I wonder if this period of time is difficult for anyone else who's really sensitive to light?

I ask because the last three days here in Toledo OH have been very overcast, so mentally I've been waking up later in the day. THEN TODAY, I got a huge blast of sunshine this morning as it was a VERY sunny day.

Perhaps because my system isn't used to "waking up" till later in the day, I FELT SUPER TIRED TODAY AFTER GETTING 10 PLUS MINUTES OF EXTREME SUN EARLIER THAN NORMAL.

Maybe I can equate it to...say...the dead of winter...after having done sunshine therapy at 9 am for a week...to all of a sudden switch to 7 am one day. I think I'd be pretty tired on that 7 am day. MAYBE THIS IS THE SAME THING I"M FEELING WITH SPRINGTIME SUN AND CLOUDS.

Anyone have any words of wisdom?
