I think it might depend on how much lubricant the consultant uses. It felt like I was wiping away masses once mine was done. Think of it this way, the size of the scope going in is soooooo much smaller than what we expel coming out on a normal day

My colonoscopy was a morning appointment (9.30am) so I was allowed to eat a light breakfast and a light lunch the day before (nothing solid after 12.00). The first dose of Plenvu was to start at 5.00pm and the 2nd was supposed to start at 7.00pm, however, it was sickly so I started mine an hour later when I could manage it. It meant that the morning of my colonoscopy I was due to leave and drive to the friend who was taking me at 8.00am and I still had a little bit of diarrhea but nothing that stopped me doing a 30min drive.
My instructions allowed me to drink clear liquids up to 2hrs before my appointment so I had sieved some chicken broth and drank all night (mainly because just drinking water was making me feel weak and I needed something to boost my energy levels!). I also drank my Plenvu a mouthful at a time with a mouthful of strained soup or flavoured lemonade inbetween to take away the taste! I did quite a bit of research into the Plenvu instructions that various hospitals in the UK give and they vary dramatically so I guess you have to go with what you are sent. Mine for example did not state that you could drink even water whilst drinking the Plenvu but I didn't read this restriction on other hospital info sheets so I went with drinking soup inbetween mouthfuls to get me through. My hospital also sent me a leaflet that stated only 8 items I was allowed to eat on the low fibre diet for the two days before.....and other hospital Plenvu leaflets gave more foods than that (many more in some cases). I ended up living on instant mash, oven baked cod and rich tea biscuits for two days

I also didn't manage to drink the whole of the second dose, in fact I only managed half. But, they say that you are good to go once what you are expelling is yellow with no bits in and I luckily had achieved this after the first dose. I tried really hard with the second dose regardless but didn't beat myself up for not managing all the second dose.
Good luck! I hope it all goes well for you!
Many thanks for taking the time to explain that
- yes, it is the fear of the unknown absolutely - and I have a fear and phobia of hospitals as it is, and I am over anxious that than the average person when it comes to these things but hey it needs done - other people have said they didn'f feels the scope going in but I am thinking you must it going in - I am sure I will
It's the plenvu once I have also - did you have some sieved soup and apple juice the day before btw?
Take good care of and look after yourself x
