Hi all, Long time no see!
I am just wondering about this NEW prep method for a colonoscopy?
Have any of you tried it?  Does it work as well as the Fleets Phospa Soda?
I swear at this point I feel like a guinie pig with these preps!
Last year it was the all new Visicol (sp?) pills, that I found substandard.  Prior to that, I've taken the bottle of Fleets Phospha Soda for the last 10 years, and prior to that it was the "GoLitely" (sp?)
Going for colonoscopy #11 on Friday.  I feel like an old pro at this at this point.  None the less, I am frieghtened, because I have lost 13 pounds (unexplainable) in the last 4 months, and my GI reiterated that I've had had UC for 21 years now, and I'm at like a 40% higher risk for colon cancer now...and he is going to take another 15-20 biopsies again, because I have Pancolitis. :-(
Any info is greatly appreciated!
Currently taking 3 Lialda (only for a month)...replaced the 9 Asacol and 2 Canasa Suppositories per day..

This was by far the easiest prep I've ever done! The phoso soda made me barf and the magnesium citrate was just as bad so I asked my GI (who a is a pediatric GI) if there was anything else and he said that the ducolax/miralax prep is the prep he uses for little kids. Although I felt like I didn't go as much as I did with phoso it was incredibly gentle and I was clear enough for the procedure.

Good luck! I'm sure things will turn out normal (or at least normal for us...) :)

I took it as well. The sheer amount of Miralax you have to take is really scary. I drank about half of what I was suppose to and then started to feel like I would throw up if I took any more.....luckily that cleaned me out enough for the scope. But, I was advised to drink it mixed with
Gatorade, and now I can't drink Gatorade at all. The tablet prep was easier for me, but I had diahrrea issues for weeks after. No issues with the Miralax prep. Good luck and I hope they find nothing.

I'm using Miralax right now and have a scope tomorrow as well. I was told to start taking Miralax on Tuesday so I wouldn't have to take so much today, which is fine b/c it hasn't taken affect until today.

I hope your scope goes well!

I did the miralax dulcolax prep as well. The volume of liquid that you have to drink is the only issue I have with it. 64 oz is just too much liquid to drink in under 2 hours. Aside from that, the comfort level was ok.

I didn't use the gatorade because I like gatorade and wanted to continue likeing it. The first prep I had was a gallon mix of "Go-litely" and lemon crystal light. Go-litely is a joke. . .I think the Dave Barry thread somewhere on the board refers to it as "Nuclear Laxative" and it's SOOO true. To this day I can't even smell lemon crystal light without gagging!

drink it slowly but consisently over ice through a straw with something you do not want to drink again. 
I still barfed, my sister barfed.  It was so hard to drink after barfing it up, so start very early.......sorry wish I could say it was ez!
I wish I had the phosfo soda, that is the only prep where I did not hurl.

I vote against Miralax and gaterade - never drink gaterade again!!

Over the years I have prepped only 4 times - not sure what two were but I never threw anything up.  With Miralax I got 1/2 way and threw it up.  Did not get much more down.  YUCK!

on the postitive side,  i think that taking 4 dulcolax pills and doing the myralax in 64 oz of gatorade is the BEST prep out much easier and dare i say more pleasant than anything i have ever been forced to do before...i recommend this prep to EVERYONE!

I did the Dulcolax/Miralax prep for the first time in April this year, and I would definitely reccommend it over the other preps.  I have had several colonoscopies with most of the other preps, and this was the first time I did not throw up the prep! I also agree that keeping it cold, using a straw, and using a Gatorade flavor that you may not want to drink again is a good idea.  It did not clean me out as well as other methods, however, but my GI didn't seem to mind.  I would start it as early as possible, as I was still "going" the next morning right before the procedure.

This prep was much easier for me. I had my first colonoscopy at the age of 49 w/ the percrip mixture and I was only able to get about 3/4th's of it down. Last Sunday I did the Dulcolzx/Miralax prep w/ gatoraide and found it much easier.

I couldn't take the phosphosoda or miralax either. The osmoprep pill prep was rough too at first (tastes like solid phosphosoda) but taking it with coke helped. Happy/sad to report I am still drinking coke.

I'm getting a scope on Wednesday and I just found out that I'll be doing the miralax/dulcolax prep.  I'm happy there aren't any suppositories with this prep.  One less thing going in my butt the wrong way.  All the suggestions should prove helpful to me.  I normally drink gatorade, so I appreciate the advice not to use it.  Maybe I'll try some lemonade.  Thanks alot everyone!

You need the electolytes in Gatorade - that is why it is prescribed that way.  I was told Powerade is ok and better.  OR pick a flavor or gatorade you never want to drink again.

Lucky me, I can use any flavor of Gatorade because I hate the stuff anyway. If I were to do this prep again, I'd start earlier and drink the stuff more slowly. It did make me throw up, and I believe it was from just to much fluid over too short a time.
