bowel preparation
"It wasn't too bad.  Mixed with propel water after chilling both mix and water in freezer for 10 minutes.  I think this helped reduce the bad taste.  Drank it down in about 3 minutes with a straw, followed by two 16 oz glasses of cold water which took about 5 minutes.  About 20 - 30 minutes later started coming out the other end.  It subsided in about 2 1/2 hours went to bed, slept okay except there was a little gurgling all night.  Next morning got up and did it again, with the same results.  I will say I think I was cleaned out after the first round."
