"This stuff is pure poison and has nearly killed me! Tastes horrible the first go round and you start vomiting on the second bottle.  I only used half of the second bottle and diluted it with water but couldn't even finish that. Drank more water and had to sit on the toilet all night.  Four days later I'm still unable to eat anything and having diarrhea! ! NEVER AGAIN! I will die first.  Whoever created this stuff should be forced to drink a gallon of it and see how wonderful they feel. I've taken Golitely before. It was awful but I felt MUCH better the next day. Four days of agony and I can still barely function. No colon cancer but this stuff just may kill me anyway.  I am a 67 year old woman who is 5'5" and weighs 150. Dosage is too much for  me"
