bowel preparation
"Started the first dose at 3:30pm. By 4:45pm I had 3/4 down but had to quit because I was gagging and almost throwing it up with each drink.  It's 9:20pm and nothing has happened yet. I feel like I have to go but nothing is happening, like I'm constipated. I'm worried because I know they will stop the procedure and make you come back if you aren't cleaned out.  I have my second dose planned for 4AM. Hopefully it is working by then."
