I have a colonoscopy scheduled for Friday (August 5). The closer I get to the date, the more apprehensive I get. Ive never had one (I'm 60) so I probably need one. It's just I'm so hypersensitive right now. I read about one guy on this forum saying it took him over a year to recover. The prep is Prepopik. I looked up the ingredients: sodium picosulfate, magnesium oxide, and anhydrous citric acid. I read about some of you brave souls having it done without any kind of sedative. I'm not sure I can do it. On the other hand, I need to be careful about anything that would affect my GABA receptors ( I'm in Valium withdrawal). Any suggestions on something mild? Any experience with this?
