I am sugar sensitive so the prep usually consists of taking laxatives and MiraLAX and a clear diet for a period of time before your procedure. You can use sugar free jellos (none with red dye so usually go with green or orange), sugar free Gatorade (not red), broth/bullion, sugar free popsicles (no red), etc. I believe you can have black coffee and tea up to a certain point (may be able to add sugar free sweetener). After the prep, you can’t wait to get the procedure over with so you can eat solid food again. I really hate Gatorade because I associate it with colonoscopies. 🥴

That's a question for your healthcare provider, especially if you are taking medication.
