I can only credit people on here for the hints (If I knew how to search for threads I'd link)
Stick to the diet - if your bowel isn't clear they might send you away and you have to do it again.
Get some moist toilet wipes and sudocrem (Best advice I think!)
The moviprep worked for me in about 20 minutes- and it was sudden! Stay near the loo once you take it.
Once it really got under way, I had my ipad, audio book, diffuser in the loo with me and I more or less stayed put.
Some people find the moviprep very unpalatable - it's not very nice but I managed it. Keep drinking water whilst you take it. I was sucking boiled sweets inbetween. (leaflet said barley sugar but I couldn't find that)
I stuck to the times I was given 7-9am and 7-9pm the day before and I actually had a good night's sleep.
It was still working next morning and I was a bit worried about journey to hospital but got there with no "accidents". Hospital is only 15 minutes away.
I was taken right on my appointment time at 9.30, chat with nurse, and the procedure started at 10. I was having a gastroscopy at the same time and had to have double sedation (not sure why- I was woozy from first dose). Out at 11 and they called DH to collect me at 12.20.
The leaflet said to bring slippers and dressing gown but that wasn't needed as they wheeled the bed from the prep room to theatre to recovery.
I did have a couple of accidents after the procedure - just had no idea it was coming - but obviously the nursing staff were well used to it and didn't bat an eyelid.
I felt really well afterwards - no after effects. Had a nap in the afternoon but was back at work next day.
Hope it all goes well for you.
