Sadly, many of our vitamins and supplements come from China.

Thanks, kayjones. Yes - I've read those reviews, and from what I've seen, every prep product has "fails". People don't follow instructions correctly, or maybe just have abnormally slow systems. But I've also seen reviews of this product - and others - that are wonderful. Also, I have a large hiatal hernia, so even the Miralax option (8 ounces every 15 minutes) would probably be difficult for me. This Prepopik sounds doable since you are drinking the clear liquid of your choice at a rate of your choice! But I was just interested in the timing of the second dose, which I haven't seen in any google search I've done.

Gabby, you should talk to your doctor about your concerns. Maybe you can take the second part much earlier than he previously suggested.

YES, YES, YES, I used Prep-o-pik for my colonoscopy a couple months ago. It's the easiest stuff on the market for colon cleansing in advance of a colonoscopy.

I had my procedure done locally, so I didn't have to worry about travel time after the second round of it.

You can make it easier on yourself by watching your diet in the days leading up to starting the cleanse. The less that goes into your body the week before the exam, the less that needs to come out. Eat low-residue foods - there are lists of such foods on the internet.

Thank you ladies for your answers! I needed that reassurance! I did talk to a nurse in the GI clinic; she was very helpful and kind. She kind of left it up to me - the timing of that second dose. I'm thinking of taking the second dose about 8 hours ahead of when we'll need to leave for the clinic....I know that the current research indicates that the closer to the procedure that the second dose is taken, the better it is, but 4 hours seems too close, maybe...If I do 8 hours, I'll have to get up early, but the peace of mind will be worth it.

I am doing the low residue diet starting Monday. My clinic only requires a basic low fiber diet starting tomorrow, but I've heard very good things about the low residue diet as far as helping the process....we live in a small town (metro area is about 3,000), so we only have basic medical care here.

I'm going to check out movies from the library to watch on the computer. I don't normally take the time to watch movies, so I'm kind of looking forward to this down time, even if I'll be in the bathroom for much of it!

I had a colonoscopy last month and I used MoviPrep which sounds similar. The first part taken at 6pm the night before, the second part 6 hours before the procedure. It tasted like lemonade but a little salty. I refrigerated it and used a straw which helped. Each time you had to drink 32 oz.....8 oz every 15 minutes. The best thing you can do is eat a "low residue" diet (Google it) for a few days before prep day and eat very lightly the day before prep. Your stomach won't have much to get rid of making everything easier. I had no cramping. I parked myself on a chair in our bedroom about two feet from the bathroom and watched TV when I felt it was safe to leave the commode, otherwise I stayed put and read magazines.

Yes, the second part went faster and was more like water at that point. Ask if you can do the second part 6 hours before instead of 4, but I still had to go just a little bit when I got to the hospital 20 minutes away..nerves maybe at that point?

Good luck.....the whole thing wasn't nearly as bad as I anticipated.

Moviprep is more nasty stuff to drink and on a schedule. My dh had a hard time with it. Prepopik is only 5 ounces for each dose, and after that any clear liquid (no reds or purples) of your choice, and on your schedule. 40 ounces the first time, 24 ounces the second time.

I admit - I am probably more concerned about needing to "go" while driving to the clinic rather than the actual process. Prepopik sounds relatively easy, I've got fun food to eat during the low residue diet, and lots of fun stuff to do while I'm "going". I am hoping that by doing the second dose at 4 am (9 hours before we leave) I'll have a "safe" commute.

Trying not to get too graphic, but anything that might come out in that last hour is going to be minor amounts of liquid. You could wear a menstrual pad on the trip and that should be more than sufficient. You should also have one ready for the trip home.
