When I did the laxative tea, I waited until I got to work. Pepe is right, it had me cramped up alot, which was uncomfortable. As long as you don't eat you probably can do the SWF (Salt-Water-Flush) at work. I agree that the enemas may work best for your schedule. I would also recommend weekly colonics, during the fast.
I did weekly colonics. I did the colonic on about the 9th day and was told that I was totally full of it. I felt so good after the colonic, I felt like dancing in the street. I just found a new colon therapist that is much cheaper and more thorough. I am planning to start a long fast tomorrow. I did 10 days the last time. I know I didn't even touch the cleansing that my body needs.
