[i]Obviously you can't exactly tell when you're asleep, but you get the idea.[/i]
Although I'm not an insomniac, I've noticed it takes me far longer to fall asleep than others. I could lay in bed for 1-3 hours, perfectly settled and comfortable before I assumedly lose consciousness and wake up in the morning, while for my parents and friends it can take as little as 1/2 an hour before they're out cold. (As for my brother, he can sleep just about anywhere within 10 minutes).
So, just a general guess for you all, how long does it take for you to fall asleep once you're in bed?
