Polyethylene glycol 3350 with electrolytes
"ABSOLUTELY foul. Don't let these reviews fool you where they say it isn't that bad. I struggled with completing the first half of the gallon bc the taste is ATROCIOUS- very very salty and no, the Crystal Light Lemonaide doesn't help. All the science in the 21st century and nothing has come up that's better tasting or easier to get down? I'm LITERALLY awake after spending a tremendous amount if time in the bathroom pooping liquid that after all my efforts isn't CLEAR yet but the thought of drinking this next half makes me want to break into hives and a profuse sweat. Would I do this again? Heck no. If I God forbid get bowel related illness, then take me home sweet Jesus, bc I can NOT go through drinking this again."
