I've discovered something about kicking the opiates. My habitual inability to sleep on my back is magnified by a lack of sleep-inducing drugs. Right side still hurts immediately. Left side hurts after several minutes. I've even contemplated turning turtle, but somehow lying with my entire weight on the surgical seam sounds just nuts.
So now I'm on the couch with Spike, where I can at least prop myself up comfortably. At some point sheer exhaustion will take hold, but at some point I need to be back at work, too. Even when I am in health I occasionally have a sleepless night, so I'm not too worried. I'd better crash hard tomorrow night.
