Hi everyone, Lucky me, I am prepping for a colonoscopy as I type this. I am on the dulcolax pills and 527mg of miralax. I've read how it is tasteless but there is definitely saltiness to it and unfortunately I did barf it up earlier today. It seems better than the other stuff I took years ago but I am unable to finish it. It worked immediately and I'm going "clear" but I am not convinced that tomorrow I will be colonoscopy ready. I've read many posts here about people being turned away and that is my worst fear right now. I should mention that I have ibs-d and had d last night. I am also underweight...maybe I don't need a prep of 527mg. Any feedback would be greatly appreciated as I am freaking out now. Thanks for your time!
