"60 yr old female.  Second colonoscopy; first time using Prepopik.  Dr instructed me to take 2 Dulcolax at noon day before procedure.  That started the ball rolling!  Then at 5pm first dose of Prepopik.  I started drinking water right away.  First cleanse started about two hours later.  It lasted a few hours.  Took second and last dose of Prepopik at 10pm.  That cleanse came in about 2 hrs.  Lasted about 2 hrs.  Procedure next day at 10am was successful.  Prepopik worked for me.  The Dulcolax certainly helped."
