I have done the Miralax for the past 5 or so years. (I get scoped annually.)
My doctor just says to mix it with any clear, non-carbonated liquid. I have started to mix the whole thing with water (64 ounces - do check the "gallon" thing as noelhelp mentioned) and then I, too split it up. I add different crystallight or "iced tea packet" things to the different containers. The last two times, I drank a lot of it just with water! (It does taste a bit like plastic.)
I, too, get cold in the way you describe. That's the thing I hate the most about it all! So, especially when it is winter, I do not refrigerate the mixture, just leave it all out on the kitchen counter. This past week I still got cold, but not quite as bad. I also drank hot herbal tea (about 8 cups of it, different kinds) sipping the prep and then the hot tea.
Good luck and I hope all this helps some!
