I've just woken myself early after gaining enough conciousness to check the time, as I have things I need to get on with and now my heads a little groggy.
So what is it we're fighting against thats trying to keep us asleep?
Is it the same thing that makes us feel groggy until we wake up fully?
What makes it harder to do when you're more tired?
