Interestingly, Oreo has been far cuddlier with me lately as well. I don't know if he feels a bit ick, if he senses that I don't feel too hot, or if it's just coincidence.
The past week seems to have been especially "foggy" for me - I've been needing/wanting to sleep much more than usual, my brains aren't working quite as well - lots more forgetting, total attention lapses, loss of focus, and general duhhhh-ness. My pain levels have been a bit higher too. And I've been disinclined to do much besides stretch out in bed or on the couch and read. I'm not really depressed, though a bit disgusted with my inertia, just, I guess exhausted. I certainly am finding it harder to motivate myself to do much. Hopefully I'll snap out of it soon.
