Are they working?

Them pills do work
Them pills don't work
I cannot really say
But yes, I feel happy today!
Is it them pills or is it the day?
Is it the bright sun shining over my head?
I am not really certain but perhaps
I can say I am doing okay!
I find myself writing after a long long time
Am I finally awake?
I hope so, I ain't sure
but this much I can say
I do feel happy today!
