Excessive sleepiness.

I think I may have accidentally ingested gluten yesterday because today I had a headache all day and then felt the need this afternoon to take a 3 hour nap. My son said that my daughter had dropped some pie crust crumbs from one of the other pies onto our gluten free sweet potato pie, but I did not heed his warning and ate some of it yesterday afternoon.  I should have listened, because it just about wiped me out today.  When I woke up, I still had work to do which I'm finishing up right now at 9:53 p.m. on a Saturday night (not fun) and I still had to go to the grocery.  Ideally, I should be baking the cake for tomorrow and the cornbread, but am I?  No.  As usual, I'm working.  :-(
