I know this isn't really an AIBU topic, but it seems to get the most response when posting here hence my reason for doing so. I have a colonoscopy booked for the morning and I have to drink 2 litres of the most vile drink known as Moviprep. It's supposed to clear you out in order for the bowel to be completely empty for the procedure, but I just don't think I can drink it all. I have until around midnight to consume it but it's soooooo vile, it's already making me heave when I take a mouthful. I hold my nose when I sip it so I can't taste it fully, however, the last sip made me heave so much that I think it's going to come up rather than 'go downwards' to do the job it was meant for. Has anyone else ever had to drink this and if so, are there any tips on what I can do to get it down?
