The lady told me to chase it with apple juice so I drank a sip then a sip of apple juice and kept doing that it helped so much! Good luck prep is horrible!
You can have a prep that is less than a litre but have to drink 3ltrs of plain water. I can drink water easily so do this prep now. I couldn't hack the 3 litre anymore.
Make sure you keep walking after drinking each glass. Helps get it through the stomach and into the small bowel faster - less chance of feeling sick or bloated.
