I just did SuPrep (liquid) with Sprite. Tasted nasty but wasn't that much volume and did the job. You don't really need to buy anything b/c you can't eat anything lol. It sounds from what I've heard that the tabs are easier going down but can induce some awful nausea - two people told me that. I think for that reason I'd just stay with the Suprep liquid.
Colonoscopy was a breeze, plan to be able to nap after it - I was extra tired, but totally back in action the next day.
Is your doctor suggesting all the meds be OTC? I had a very easy process with the Rx called ClenPiq. No need for "extra vaseline" as you referred to up thread.
I have a colonoscopy scheduled for end of March. GI doc suggested Gatorade and MiraLAX because the volume to drink is more BUT the MiraLAX is tasteless and I can prep ahead and make the drinks cold.
Taking all suggestions to make this as easy as possible. I get migraines and hypoglycemia and any tips or tricks or weird suggestions - please share! I did read to get some Vaseline in case my rear is sore lol.
