I suspect I am rather the expert on Bowel Preps right now as I had to do 2 of them within one day of each other in August.
I am not familiar with the prep you are taking but I know the one my Dr. uses brings you to your knees. Bisacodyl is an OTC medication - laxative. If you write out your whole prep I may be able to help you better.
This is one of those times that you have to take the prep in order to optimize visualization of your bowel so there is no use having the test if you are not clean out as the GI Dr. will not be able to see with her/his scope.
