Has anyone had plenvu for a colonoscopy? I have the colonoscopy on Saturday morning. I think they said I have to drink 500ml plenvu plus another 500ml clear fluids with the first sachet at 5pm then another 500ml prep plus 500ml fluids at 9pm .. I'm not a big drinker at the best of times I don't know how I'm going to manage 2 litres in 4 hours 😩 can I drink the likes of coke or lucozade alongside it or are they out? I forgot to ask
