"DIARRHEA. Remember that word, because if you take this stuff, you will be suddenly awaken during the middle of the night and forced to wreak havoc on your toilet bowl. I just blew up my toilet 45 min ago and am getting ready to pay it another visit as I write this. If you are reading this review, take my advice: use something else.  My cough was bad, but I would have gladly kept it if I knew my butt was going to turn into Niagara Falls."
