Although a bit of a personal issue, I’m known for my transparency and I’m happy to share the experience so that others approaching 50 know what to expect.
The preparation is the hardest part. Three days before the procedure, it’s recommended that you reduce the quantity of high fiber foods you eat – fruits, vegetables, nuts etc. For me that was particularly challenging since my entire diet as a vegan (who tends to avoid white flour, white rice, and white sugar) is high fiber. I moved to soups and brown rice. A day before the procedure (really 36 hours), you move to a clear liquid diet – apple juice, broth, and tea. In my case I drank a cup of vegetable broth and apple juice every 3 hours.
At 7pm the night before the procedure, the real challenge begins. The bottle of magnesium citrate reads “a pasteurized, sparkling, laxative”. Sounds so appealing. The first dose is 15 ounces. The bottle warns that the maximum therapeutic dose is 10 ounces in 24 hours for adults, but colonoscopy is a special case. The 15 ounces of laxative is followed by 24 ounces of clear liquids over the next 2 hours. Keep in mind that you have not eaten any solid food for 24 hours at this point. Sparkling laxative followed by broth and apple juice is not Chez Panisse.
