I have been through this twice, what made the biggest difference and things much easier was massively reducing my diet 2/3 days before hand. I ate things like toast, eggs and cup soups, you want as little fibrous food as possible so avoid veg and legumes etc.
My first time I didn’t heed the diet advice and I paid for it when it came to the prep. Having learned my lesson, second time round prep was much quicker and easier because of the restricted diet.
As for drinking the Movicol (if that’s what your having) like others say it’s much easier to get down cold. I added sugar free cordial to mine and it was ok, I also had a cold glass of sparkling flavoured water to sip in between the prep. For hunger I found sucking/chewing ice cubes helpful.
As for caring for you delicate bum hole and it will be sore if you wipe all the time I recommend getting one of these
Deal: CROING - 40 x Sinus Rinse Mix + 1x Nasal Wash Bottle (300ml), Neti Pot Kit amzn.eu/d/1XhvKCK
Instead of doing lots of wiping you can fill the bottle with warm or tepid water and use it to rinse yourself. My second recommended is to get a pair of tena pants, the full pull up type pants and popping these on after you think the after affects of the prep are done. They will allow you to crawl into bed and get some rest without worrying as it can often feel like your not done when you are, so instead of spending needless uncomfortable hours on the loo wondering if your really finished you can use these to help you get some rest.
Hope all goes well, it’s really not so bad. 💐
