You know the feeling all too well — drifting off into what you hope will be a long, restful sleep, only to be abruptly woken an hour or two later by that all-too-familiar urge to head to the bathroom. You stumble groggily, half-asleep, make your way to the toilet, do what you need to do, and then crawl back into bed, expecting that sleep will resume. But just when you finally begin to nod off again, your body insists on repeating the ritual. By the time morning comes, you technically have slept, but the result is far from restorative. You feel exhausted, foggy, irritable, and frustrated, as though your body has played a cruel trick on you overnight.
