Movicol should be the UK version of Miralax
I think
If so you can add it to any hot or cold beverage
Tea etc … stir well and then there is no taste
Ask the chemist (pharmacist ) for the uk version of miralax .
Other things magnesium citrate if you ask your doctor on how much /how often etc … but that works quickly just with a lot of abdominal cramping /pain
You will need something for clean out for the colonoscopy as well
My adult child was dx at 7 and tends to be constipated unless he is on daily miralax .
His current drink is orange Gatorade that he adds the miralax to .
Water just tastes gritty
We have used koolaid before as well as lemonade .
