"After having two other colonoscopies  I suggest  to drink this without any flavoring,  it taste much better that way.  Adding the flavor only seems to intensify the salty taste 
 I divided the drink up in the 4 quart containers and drank 1 at a time much easier to do.  Drink  it through a straw.  You have less chance of becoming nauseous . I coated my rump as  as suggested by others  who had the prep. It really helped. P.S.  Thank you to all the people who offered suggestions it really helped.  I also drank the prep at room temperature and chilled.  The only difference was at room temperature it was a little bit more salty.
 If you’ve ever mixed baking soda and water for heartburn  that’s what this prep reminded me of but, actually tasted better.  It was not horrible.
 At the end I replenished with Gatorade. 
I also had 3 more clear BM’s the next day  which was the morning of my procedure.  So you might want to wear a protective  pad or something like the depends  or take an extra pair of clothes  in case you can’t get to the bathroom fast enough."
