It was an experience - the worst part being the two "preparation". Day1 was cutting down on all the good LCHF foods we (should) enjoy, eating white chicken, white fish, no veg, no fruit, no tea or coffee or anythings that may have "coloured" output. The day before was a powder 3 times and nothing solid to eat after a very early breakfast from list list of the day before. Surprised I wasn't hungry, nothing much happened till approx 14:00. No detail but, for those who may have future colonoscopy a word of advice; do not sneeze, do not cough unless "enthroned in heavenly splendour". No problems today, just good to have the results,and be able to manage it,with no drug intervention. Have a Google search on "causes of diverticulitis" and wonder.
End of update. Do not be fearsome over this procedure - it is an investment, not a cost.
Thank you all so much for your support and encouragement - it really does help.
