I'm thinking Spring Fever too. I've been making stupid mistakes like horrible grammatical and spelling errors when I'm usually meticulous with that stuff. I leave out words so the meaning of the sentence is completely altered. I can't remember how to spell certain words. I say stupid things like "Like the plates clean" instead of "lick".

At work, I haven't been able to concentrate worth anything. I get easily distracted. I am on a crazy deadline for stuff at my one office but I can't focus and get done entering the data to save my life.

I think it's Spring Fever, even though I'm hoping to have one more big snow before the warm weather arrives.
