bowel preparation
"Yup, it tastes foul but you knew that already. Unfortunately I didn't read these reviews until after my first dose and didn't think to chill it prior. Big mistake, I'd rather eat liver and onions for a month than taste this evil concoction at room temperature again. Took my first dose at 5pm after a liquids only diet all day. No bloating on the first dose and very light nausea. Took about an hour to kick in then the fun began. Major gas at first - even the dog left the room - then the 15 second dash to the loo every ten minutes for FIVE hours. I'm not exaggerating in the least. Second dose at 10pm was even worse. Finally got to sleep around 4am for a 6:30am procedure. Does it work? You betcha but it is not pleasant."
