Am new to this web site.  Am having colonoscopy prep on Monday, and am supposed to use Miralax/ducolax prep.  Have used fleets, Visacol, & phosphosoda - all have been horrible.  Does anyone have input on using this?  Am very nervous, as I get very sick.  Any info. would be helpful.  Thanks!

My 17 year old son just did this prep a couple weeks ago and said it was very tolerable. It is also the prep they often give kids and most do very well with it. My son liked it much better than the GoLytly.

I bet you'll do just great. Let us know how your scope goes. You'll be in my thought and prayers.

I did the Miralax/ducolax prep. Wasn't too bad. Mixed the Miralax with orange Gatorade. Didn't make me sick, though I didn't want to drink orange Gatorade any time soon!

Of the various preps I have experienced, the Miralax/Dulcolax was a cakewalk compared to the others. The only problem I had was the sugary gatorade - much too sweet for my taste buds. I will switch to something else next time - perhaps just water.

Not to scare you but it made me very sick. I think the dulcolax didn't do anything until I was already empty and it made my stomach cramp up but there was nothing left to push out. I ended up on the toilet with cramps, throwing up into a garbage. Next time I will ask for something else.

Never had the Dulcolax with Miralax. Good thing cuz I did not need it. The Miralax worked just fine and it started on me about half an hour after I started drinking it. It cleaned me out good! However, none of the preps are fun. I do think the Miralax was the better one though.

That's what I had to use. I mixed the Miralax with Crystal Light to avoid drinking a ton of sugar. I threw it all up, though. I had been very nauseous for months, though, so I knew I probably wouldn't be able to keep it down. I was also so sick at that point that I really had nothing to clean out, so it ended up fine.

I found that the Miralax didn't really have a lot of taste, so I mixed it with water ahead of time and got it ice cold, then drank it through a straw. I had a little trouble with throwing up at the end, but I think that's because I tried to drink it too fast.

Thanks to all for your replies - they wree very helful. I found the miralax/ducolax prep to be tolerable, and much better than the others. I did have trouble getting all 64 oz. down & threw up some, and it took me a long time to finish it all. I did 1/2 gatorade & 1/2 crystal light. Did have some nauseua. However, this was the first time, in 4 procedures, that I didn't go into the procedure horribly sick, and have been feeling relatively ok today, afterward. Thanks again to all - this is a very helpful website!

I'm new here but have a lot of empathy about the different preps. All the liquid preps gave me nausea and vomiting. My doctor gave me OsmoPrep Tablets. You have to take 32 tablets (not all at once) but you can take them with water, ginger ale, gatorade. You still need to drink quite a bit of liquid for the flushing out process, but at least it's not a salty liquid. Some people don't care for them because they have difficulty swallowing pills, but I much prefer them to any of the liquid solutions. You still need the enemas.

Current meds: Azasan 150mg, Asacol 2400 mg, Tincture of Opium
The best med I have ever used for chronic bleeding of 5 years was Budesonide (short chain fatty acid enema). It was difficult to find (has to be prepared by appointment and not every pharmacy has the ingredients or expertise), very expensive, not fun to administer, but it stopped my bleeding in one month, I tapered for two months and I haven't had a recurrence of bleeding for a year and a half.

I did this one last time, it made me kind of nauseous. I actually refuse to drink Sprite Zero anymore cause that's what I mixed my prep in.

Just try to drink it as cold as possible.
