Urgent colyte advice needed

I'm confused now. I have to start drinking the colyte in a few hours. Instructions that came with colyte say just mix with water. Pharmacist and other instructions I have say mix with crystal light for flavor. I know it's going to be difficult for me to keep down as I am very sensitive to bad tastes. I did get raspberry lemonade crystal light, but how much do I add, and should I add it or try to drink it straight? I got straws too. I am taking dulcolax as well, and bought a bottle of miralax just in case.

So what's the lesser evil with the colyte? And if I can't keep it down, do I mix the miralax with anything and how much/how often do I drink that?

Does plugging your nose while you drink help? I've only ever done the fleet phospho stuff before and that barely stayed down. I'm really worried. I just want to get this over with.

Thanks for your help!

I use Miralax because you can mix it in any liquid and it is tasteless.

Oh is the rasberry red colored?? Mu doctor said nothing with red or orange coloring. I just held my breath tight and chugged it and then chased it with water. I hope you are able to get it down!!!
