My last prep involved Miralax, and after numerous accidents, I decided that if I go that route again, I'm starting the prep much earlier in the day, and starting the liquid diet a day or two earlier. The best prep I took involved a suppository, and drinking a bunch of semi-icky stuff. Unlike other preps with heinous liquid drinks, I was able to keep everything down, and by the morning, I was clean. The miralax kept me up all night on the white throne. I tink I might have gotten only 2 hours of sleep (and that was on the loo! LOL!). I think my problem with the miralax was that when it started to work, it wasn't a "Hey, you should probably go to the bathroom soon." It was more like "Hey fool! You should'nt've left the bathroom at all. So here's your warning...get into the loo five seconds ago! Hahahahahaha!" Not a pleasant experience.
In general, I'd suggest starting the liquid diet a day or two earlier than recommended, and whenever possible, mix whatever horrid drink with a little Gatorade/Powerade/Apple juice, to make the drinking a little more tolerable.
Good luck on you preps, and I hope that you only get good news from you scopes. Keep us posted on how things went.
