Jason Vale 3 day detox question

Hi Everyone

I am considering doing the above for 3 days next week - has anyone done this and if so what pointers can you share? Also, I do not have a juicer, only a blender - do you think it will work if I just blend everything as per the recipes instead? Am not going to invest in a juicer as I cannot think that I will use it that much in future.

Thanks!
