I like Gatorade and Miralax, the only one that doesn't make me throw up. I did it a few months ago and it was so easy. Just mixed it all up in a pitcher, drank a glass every 20 mins and it worked like a charm. I don't eat solid food for 1 1/2 days beforehand though just to make the prep quicker.
It has no taste, other than the taste of Gatorade.
They do tell me to drink a bottle of Mag-Cit the next morning but I never drink a whole bottle of it. I never need it, I'm already totally cleaned out by then.
