I know what you mean about the juicer; my friend did a 14 day fast and did drink regular juice; but it had to be 100% juice and it worked fine (obviously, i guess it is not a total cleanse??) anyway she lost 17 pounds in 14 days...not bad. another friend of hers did the same thing ( a guy) and did it for 40 days with 100% juice drinks and lost 70 pounds..
About the caffeine; i am on day 2 and my thought is i know it is not good for me; but to get me through the first 4-5 days i will drink half decaff/half regular; and then wean off of it...I am currently on day 2; the longest yet; i want to go 30 days at least..
