text: Yo, check it out, listen up, here's the scoop
  Got a study on cancer pain, ain't no goof
  47 patients in the mix, we rolled the dice
  Testing controlled-release morphine, that's our device
  
  They kept records, detailed, every single day
  Pain levels, meds, and side effects, no delay
  A nurse was there, watching closely, taking notes
  Making sure the data ain't just some anecdotes
  
  Out of the 47, 37 were stable
  With regular morphine, they were able
  Then we switched 'em up, to the CRM pills
  Some took it every 12 hours, others got thrills
  
  16 patients, they took it every 8 hours straight
  Doses ranged from 30 to 360, no debate
  They loved the less frequent doses, gotta admit
  And uninterrupted sleep, that's the ultimate hit
  
  All the patients, after the study, made their choice
  They stuck with this method, raised their voice
  Extended care data was gathered, no bluff
  Monitoring each patient, enough was enough
