Creative Conundrum

A ditty in Alouette form (described following the poem).

I once tried to write
all day and all night,
but I dozed off halfway through.
And what I had writ,
I have to admit,
deserved a scathing review.

So I tried again
in pencil, not pen,
and strove to aim for success.
Now, this time it rhymed,
the was beat well-timed.
But the plot was just a mess.

By that time I'd grown
blasé to the bone.
So I just gave up and quit.
I might try again
another time when
my noggin's not full of (s___).
