Hi, after reading some experiences and "hearsay" on another site. I have decided not to do the cleanse. For one, the Oxypowder costs way more than I thought it would. But, I must say the main reason for not doing it is because of the "worms". I have read that you have to "escort" them out if they are kind of large and/or long...someone saw this on animalplanet. If that happened to me I would go into cardiac arrest. Maybe one day I will get a colonic.
