I was given Plenvu (didn't realize there was a choice...none was mentioned to me), and not to be overly dramatic, but I will not survive that type of prep again. The initial flavour of the drink (16 oz. once in the evening and once in the morning for an afternoon appointment) was INTENSE SALTY. Once you had gulped that swig down though, the aftertaste was CLOYING SWEETNESS from aspartame. Trust me when I say it is many sips to the bottom of each dose and this is not something you could chug even if you wanted to. (I briefly tried and can usually power through stuff like this.) I got through the evening dose, but faced with doing the same thing the next morning, my body was rebelling. It took every ounce of my being to keep that stuff down long enough for it to work, in fact, my new "induce vomit response" thought is the taste of that intense salt/sweet combo.
But that wasn't the worst of it for me...THE CHILLS...OH MY GOODNESS THE CHILLS...that started within about 5 or 10 minutes of starting to drink it and didn't fully subside until midway the day after the procedure. I had SO MANY blankets on my side of the bed, just to keep warm. When I got to the hospital and hopped into the bed, the nurse brought over a blanket from the warmer and I told her that it was the first time I had been warm since starting the prep. When they woke me up right after the procedure, I was shaking uncontrollably. The same nurse said, "Are you cold?" but never went and got me another warm blanket, because at that point, they are just looking to get you out the door.
That was for my first procedure. You had better believe that I will be asking for something different when I go back next time, and if pills are an option, I'm getting on board that train. It would be hard-pressed to be worse than what I had the first time.
