definitely see how long the SWF (Salt-Water-Flush) takes for you on your days off, and then gauge it from there. I'm starting the cleanse tomorrow, but the first time I did it I was all done about an hour after the SWF. you'll quickly learn not to leave the house until you're done, and it'll probably mean waking up a bit earlier than you're used to in order to ensure that you give yourself enough time. good luck!
