Ode to my evening beverage

Drinking, drinking lots of tea
Even though I'll have to pee
Right before I go to bed
What's going on inside my head?
"Such foolishness is sad," I said

My bladder soon begins to slosh
"Oh, no," I say. "Oh, no... oh gosh!"
I narrowly avoid the worst
It's not the last, and not the first
Yet soon again I'll quench my thirst
