I believe that I had to drink one more bottle of the fleet soda and then that still didn't work so I did the enema, several times, finally worked. I did not drink a lot of water at the time because my guts felt like they were going to explode and I didn't want to add anything else to the mix. I actually did have quite a bit of pain, that is why I called my doc (and the fact that it hadn't come out yet) and that is when he told me to do another bottle, luckily I had another bottle on hand because I was in no shape to go get one. I would suggest that you do call your doc and let him know this is happening, you are drinking this stuff for a test or something aren't you? Would probably be something he needs to know. I hope it passes for you soon. Take care,
