Had one this past September and my doctor didn't use that stuff..............just several dulcolax twice the day before (10 a.m and 6 p.m) plus 2 bottles of magnesium citrate (you buy at Walgreens) in the evening. Works great and way better than that powder stuff. You can have lemon jello and broth that day also. No 3 day liquid diet required. All just the day before. You should ask your doctor about allowing you to do the above. Some who do that powder stuff don't get fully cleaned out.....then they make you come back in another year or 2 because the readings weren't that good.
