"I've used many colonoscopy prep regimens and this is one of the best. My #1 choice is Pico Salax, which tastes good (like Tang), but is not available in the US. After that I'd prefer pills but those have never been an option for me. Suprep ranks next.

I have chronic severe constipation so I took an enema and Correctol in the days leading up to it. 

I am infamous for not being able to keep colon prep solutions down. I am a BIG baby when it comes to drinking colonoscopy preps. 

I chilled the solution and dulled my tongue with ice first--the whole tongue--sides, back, tip, etc. Then I drank it and IMMEDIATELY swished my mouth out with straight lemon juice (like you would with tequila!). Then Listerine. It stopped me from gagging."
