Sunday Night Solution...

 Sunday Night and You Feel Like…
 
It’s Sunday night
And you’re not quite right,
And Monday’s in the warning.
 
But how the hell
Can you feel well,
And be up and about in the morning?
 
So do be wise,
And exercise,
You’ll soon be feeling better.
 
You’ll quickly see,
How you can be
A morning-time go-getter.
 
And that’s the trick,
When you’re feeling sick
In the evening on a Sunday.
 
Decide instead
To use your head,
And brighten up your Monday.
