Prepopik
"I have to have scopes yearly, so I've tried several different types of preps. After trying Prepopik, I will never use anything else! It's the only thing that doesn't make me nauseous and also not having do drink much of it to get the job done is awesome! I will say that you have to make sure that the solution gets warm before drinking it, or it won't work as well. I think the frustration comes from people not reading the directions. :) Prepopik is amazing!"
