Good luck for tomorrow. The procedure isn't wonderfully pleasant but isn't awful. Make sure that after swallowing the liquid dynamite, that a toilet isn't too far away and that there is plenty of toilet paper. Also, a tube of Savlon is welcome relief. You can ask to be semi sedated so have that. I watched the procedure on a monitor and the doctor
Explained it all to me which was facinating looking at my insides. Afterwards, the nurses will look after you and bring you a nice cuppa and something to eat and you will be allowed home when the sedation has worn off.
Make sure that your basal rates don't make you drop low.
