To Rue the Flu, or, The Song the Sick Man Sings

A Limerick that defies the rules of its genre for you, composed in view of the medicine cabinet,

I rued the day I got the Flu
I rued it through and through
And then this day,
It went away
But, alas, the Flu fought through

It made it through two days it seems
And now I have the chills
My fever marches,
"Onward lads!"
Past my brave conclave of pills

I rued the day I got the Flu
And lo, it went away,
So now I know,
Just what to do
I now shall rue the Flu!
