I thought that coffee was making it possible for me to go also, but after doing the Master-Cleanse and using warm water (warm enough for like teas and such) I found out that the coffee wasn't making it possible for me to be able to go. It was the fact that it was warm when all of my other intake was cold, refridgerant cold. Water, juice and whatnot. Now I can go to the bathroom by drinking warm water versus drinking coffee. In fact, I don't drink coffe anymore.
