Please forgive me if I come off sounding harsh...but what is 10 days out of your life to try something? So what if you get to day 7 and you don't get results! At least you can say you tried it and it didn't work. If you can do 7 days...why not 10? Maybe even go until you feel good! What is it that is keeping you from giving it a go? Perhaps you are so addicted to food and the security that it brings that going without it is really stressful. If that is the case then you probably need to do it more than ever!!
I don't think the cleanse is that much "agony". Sure it is about sacrifice but the potential for payback is much better than any other investment you can make.
Again...sorry if this post is coming on too harsh. But I don't have a lot of patience for people that want immediate results and guarantees from things. I think that is one of the major problems with society today is that people want instant gratification and have no patience to seek other methods.
Go for it...you can do it!! Just don't go into it half-hearted or you will fail and blame it on the cleanse.
