so tired that I'm too lazy to put myself in a reasonable sleeping position when I fall asleep...

So another random side-effect of training.... I am really tired when I get to bed, and I'll often try to keep my eyes open for a few minutes and read. Last night I feel asleep while reading, but rather then putting my head flat on the pillow (I was either too tired or lazy for that, not sure which), I fell asleep kind of sitting up and rested my head against the wall - my bed is in the corner of my room, so this is easy to do. I think I slept at least five hours like this, with my head not actually on a pillow but resting against a hard wall. I'm not a doctor, but I really don't think that was good for my neck. In the choice of immediate sleep or comfort, I clearly put a premium on the extra three seconds of sleep that repositioning myself on my pillow would have cost me....
