Reversal of fortune

I used to lie awake at night
even with the pills
praying for a goodly sleep
to cure me of my ills

but then, the greenies vaporized
and many nights of Hell
I spent, and I was terrorized
by the clock’s alarming bell

and then, the jumpy nerves were calm
and I was amply blessed
and given mind and body balm
with periods of rest

but now, with many weeks gone by
no medicine to take
I open up my drowsy eyes
but cannot stay awake.
