the tea should be a laxative tea like smooth move (you can find this on amazon.com if you want to take a peek). Do not add Sugar or milk to your tea.
For water I use arrowhead spring mountain water. Others use distilled water -- I like my spring mountain :) stay away from tap water if you can.
I did the Master-Cleanse for 15 days followed by a healthy Diet and lost 42 pounds. Sure I coulda kept it off had I not indulged in food and drink over the holidays -- it was THAT easy to put 18 pounds back on. You really do have to keep it healthy for this to work.
