"New dose, one pill took it at noon, bowel motion by 1:30 at 5pm started drinking solution every 10 minutes. Choose the cherry flavor, tasted like thick flavored water. I am glad it was cold, did not taste as bad as I anticipated. Biggest thing was drinking it, gone fast and doing it again and again - 20 minutes into it I went to my throne had to in between drinking the solution after every other glass (at least I was able to discard some and have room for more that way I was more comfortable. Was so happy when 6:10 came and I finished - by 8:30pm I went to bed and had a great nights sleep. Woke around 4:30pm for another visit to my throne did go back to bed and test went well."
