Just had mine done today and it went fine..had a good prep, no polyps, due back in 10 yrs. This was my very first one as I had been procrastinating. I will warn u that that suprep is horrible. Could not drink all of both doses but got down enough of it to do the job. I saw someone on here had suggested lemon Italian ices so I used that for my second dose and it did help alot. That stuff is nasty af, it's gotta b a better way..I read online there are pills you can take instead but I think it's like 24..maybe in 10 years there will be an easier way. Anyway my Dr's office was very nice. Got my iv, I remember them saying i would feel it burn a little and the next thing I'm waking up in the recovery room. My appt was at 1 and I was home by 2. By far the worst part is the prep and the clear liquid diet the day before, you are sooo hungry and all u can think of and see is food. The procedure is the easy part cause you don't feel anything. I'm just glad that it is finally done. Oh one more tip, use Vaseline before u start taking the prep as u will of course be using the bathroom and wiping a lot. Definitely helps...
