How to make the prep drink stay down

Hello again everyone, I asked a question before my prep, now it's during my prep.

M26, first colonoscopy

Prep in question is the 4 liter jug you fill with water. And drink over several hours the day before.

I'm about 66% through the jug, and I nauseous with getting this stuff down. The taste isn't the bad part, it is just not sitting well in my stomach.

At this point I've been passing what seems to be slightly yellow water, for about the last hour. I know I should keep going and get it all down, so if anyone has any suggestions on how to make it not upset my stomach, that would be appreciated. 👍
