Sleep deprivation again. It’s an awful feeling – fatigue, can’t concentrate, blurry eyes, a weird heaviness or pressure in the head. Coffee doesn’t help. Hangovers are more fun. Whoever invents a brainwave-altering device that allows you to get to sleep without drugs and stay there will be a billionaire. I mean, how hard could this be? We can measure brainwaves, we can see them change during sleep cycles. So where’s my sleep-inducing device?

I asked Google and there’s a lot of information about brainwave training, but most of it looks sketchy, like something you’d see on an infomercial. Sometime when I feel better I’ll read through it and decide if there’s anything promising there. Right now I think I’ll take a nap.
