Bowel Prep Second Time Around

After I vomited the Plenvu previously causing the colonoscopy to be cancelled i have now got another appointment next Tuesday. This time I have been given Moviprep.  I absolutely dreading it again.  I could not get 500 ml down me never mind 1 ltr. Only plus is i have one prep in the evening and the other in the morning.   Anyone had Moviprep and how did you find it compared to plenvu. Thanks in advance
