constipation
"Because I'm over 190 lbs, doc said I had to take Mg Citrate 2 days before colonoscopy. (The day before I also get to deal with Suprep, which is worse.) Downed the 10 oz. bottle in 4 shots, followed by 8 oz. cold water. It hit me a few hours later and then again in another hour or so%u2014don't know if it'll hit again, but all feels calm right now.  Pretty well flushed out. I had already had 3 BMs earlier today...not really unusual for me...and wasn't really full of food. The stuff definitely works. I had the Lemon flavor. Told my wife it tasted like "lemon-flavored old underwear." Really not great-tasting, but keeping it cold and holding my nose helped. Worked right through my pain meds, too. Finding it a bit difficult to stay hydrated."
