That Weird Feeling You Get When You're Sick

I'm just about finished day six of being really under the weather. I think (hope?) the worst is over, because I'm at that weird stage where I'm not coughing or vomiting as much and I just feel this heavy weakness through my whole body that almost feels masochistically "good." I mean, it's still awful, but it's like a siren call to sleep more than anything else, and when you do slip into bed (just a few minutes after I hit the "Publish" button, I assure you), it feels really right to surrender to your body's need.

Does anyone else ever get that feeling?
