  1. I’m not sure who this is meant to apply to, as hospital staff advised me to eat and drink (I don’t drink alcohol) as normal after my colonoscopy, as did the printed instructions they gave me. Thirteen hours after the procedure ended, I have consumed 4 light to medium meals of accustomed type & size (and plenty of fluids) and am feeling great. Granted, my usual diet is rather lacking in roughage, and I usually consume at least 1-2 *large* meals a day.

  2. I had my procedure this morning. I too, was told “eat normally” with no specific instructions.
    That said, i will be drinking more fluids and avoiding fruit and veg to start with.
