I was scheduled tday to have a colonscopy and a Upper GI Endoscopy, i havent eaten in 24hrs and feel terrible, i had an extremley tough time with the Klean Prep... I woke today and got called by the hospital, because of snow its been cancelled.. I am mortified. I cant go through all this getting prepared and psyching myself up again next week! Im truly distraught and am really considering calling everything off...This morning aswell i have the most incredible headache and dont feel to well at all (still feel as if KP is doing something),has anyone else who has taken the Klean Prep had this and did it go? I need to try and prevent this next week!!
