Oh boy. Good to know that I should take some time off the day before for the prep. I did some more reading after seeing your comments, and it appears as though the phospho-soda may take effect in as fast as 30 minutes! So, looks like I'll take that afternoon off and stay close to the toilet.

I'm supposed to be eating low residue through tomorrow. Enema tomorrow (Monday) evening. Clear liquids after that (7pm Monday until after procedure on Wednesday). Start the phospho-soda around 3pm or 4pm on Tuesday. 2d dose around 3am or 4am Wednesday morning. Procedure scheduled for 8am.

I am really getting nervous about drinking the phospho-soda. I am so afraid of uncontrollable vomiting! I am going to call first thing tomorrow morning and ask about the pill form.

I'll make sure to stock up on Puffs or Cottonelle wipes!
