bowel preparation
"A couple of things to add what others have said:

The label says to store at room temperature with "excursions" no lower than 15 C (59 F), so I am not sure of the wisdom of chilling the stuff. I did mix it with very cold water before I drank it.

Using a straw helped me.

I put a green apple  between cheek and gum and sucked on it while pulling the solution through the straw. That seemed to do an effective job of masking the saltiness and preventing gagging.

I did put a wall charger and cable in the bathroom for my iPad.

My experiences otherwise largely match those of the majority of people here, and as colonoscopy preps go, well, it is better than they used to be."
