Those of you who have had anesthesia since your diagnosis

How did you know your stomach was clear prior to a procedure? I had an endoscopy and fasted 12 hours. It was probably 14 hours by the time I was actually in the room. There was still food residue in my stomach. Now I am having a bone marrow biopsy at the end of September, similar thing. No food after midnight. My checkin is 7am, and the procedure’s at 9am. I’ll be getting propofol sedation and pain medicine.

I was thinking of eating light the day before, or maybe doing a full liquid diet. I will mention it to the nurse when they call to go over my medications, but I know this condition makes me an outlier, and they might not have an answer.
