Beth, I replied to your other message about the tea. It's important to get a laxative tea so everything can move out, otherwise there is no cleansing and you'll probably feel more uncomfortable as the days go on.
Last year, I did this for 10 days (with the tea only, no SWF) at 6 glasses/day and didn't notice any weight loss until around the 7th day. I lost 12 pounds by the 10th day and only regained about 2 or 3 pounds afterwards. How much we regain depends on how we eat after the fast. My diet was vegetarian before and after and together with daily exercise, my weight stayed off.
My main purpose for the fast/cleanse was for health and I would like to do this 2 or 3 times each year.
