I was praying someone could help me with this! I've been given 4 sachets of Klean prep for an operation im having tomorrow at 2.30. I've been told I have to finish them all by today. I've been trying since 12pm today to drink them and have only managed 2 glasses (normal sized, not pint sized!!!) which isn't even half of 1 sachet. They are making me physically sick and I cannot keep them down. I still haven't had a bowel movement either. I was hoping someone might have some tips on how to get this down me?! I've tried adding juice and water, drinking with a straw, drinking water straight after swallowing it and putting the solution in the fridge before drinking. Still no luck! Any advice anyone??
