I woke up at 4am to an incredible amount of pain in my stomach/intestines/back kidney area on my left side. I thought I was going to die. I am desperately seeking info on this whole flush idea. Right now I can't keep anything down, at the time i thought pepto bismal might help the pain but it just came flying back up in 5 mins. I have been sipping limited amounts of apple juice. I am reading up on this. oh my god it feels like Mike Tyson is using my left kidney for a punching bag. I can't even imagine trying to swallow Epsom Salt and olive oil in that quantity. repeatedly.
