OK so i am starting the Master-Cleanse today. I have a terrible pain in the middle of my back up between my shoulder blades. anybody got an idea on what it is? also today to start with i felt like i wanted to throw up. this happened to me before one night i woke up and my mouth was salivating and i thought i am going to throw up and than i didn't but come to think of it i have had this problem during different times when i was MCing and it made me want to stop the cleanse. cause i don't throw up it just feels like i want to . i thought it might have been because of the amount of cayenne pepper i was using which was on the high side but now i don't know i haven't even drank anything yet. what do any of you think?
