I had this same prep a coulple months ago. I ended up calling the doctors office in the afternoon because I thought it was not working. They told me the first dose does not always have a big effect and that it should kick in at the second dose. Mine did, but I will tell you it wasn't as bad as I was expecting. Do make sure you drink a lot of extra fluids. I was pretty dehydrated by morining.
