Hello I have a colonoscopy at 12 pm on Tues. I start prep on Monday. It says to start at 2 pm by taking two Durolax and 4 pm to drink first half of Peg 3350 then two more Durolax at 6 pm. Can I start the prep a little bit earlier like maybe a hour or two at most? I am handicap and fall easily so hoping I won’t be in bathroom all night on Monday if was to take it a little earlier . Thanks!
