Hi Fissy,
I'm kind of late responding here but I thought I'd tell some of my experience.
I've had to take the golytly? stuff twice last year. The first time I started way too late in the day and it kept me up all night "going", also made me throw up cause I was supposed to drink a cup every 20 minutes or so and be done by midnight.
I started much earlier the 2nd time and had much better results with it. Instead of starting when they said I started early afternoon, I didn't drink it as fast as they said cuz I had all day to get it down, no throwing up. I would drink a half a cup really fast then suck on a jolly rancher as a reward and it would take away the yucky taste. I made the bathroom trip alot, too many to remember. It really wasn't too bad the 2nd time around.
My dr also told me to be on a liquid diet the day before the golytly stuff, so I think that helped also.
After the colonoscopy, I really felt pretty good, but of course I had hemmie surgery too, so when the lidocaine wore off, I had pain from that. The colonoscopy seemed like a breeze, just take a little nap and wake up feeling good! Probably should eat mild food the first day until the digestive tract feels up to normal food.
Who came up with that goofy name?? golytly???

It's like a bad joke.
