I've done it enough times that I'm totally fine with it: the electrolyte drink tastes like slightly bad-tasting Gatorade, which is hardly worth caring about.

And you get diarrhea-like bathroom runs half a dozen times maybe.

Yes it was annoying to get the runs and gross to drink the stuff the first few times, but people eat things like cow tongue or live octopus or whatever... I can handle some bad-tasting Gatorade and some diarrhea just fine, especially given the 5 years of peace-of-mind it buys me afterward.
