Omg! I tried prune juice for the first time in desperation this morning, and I had to run to the bathroom two hours later so that I didn't let out the biggest, longest fart of my life in front of coworkers! I was in there laughing it up because it sounded like something you hear in comedy movies. Word of caution: Only drink prune juice when you know you'll be home for a while! Thank goodness I made it in time!
