Taking Movi-Prep for the first time

Okay, so I just finished my first cup of movi-prep. Seven more to go. The taste was not nearly as bad for me as it seems to have been for some people. I guess I'm lucky because I always liked the taste of salt and if I hold my breath, it tastes just like salty water =). I'm not so much afraid of gagging on the taste now as I am of the fact that it *does* seem to sit heavy on the stomach. I'm not entirely positive I can get another 3 cups of this down in the next 45 minutes. I know it's important to keep it all down or else it's pretty much worthless and I would REALLY like to avoiding throwing up. Does anyone know if it's totally necessary to take it within an hour? Can I just take a cup every 30 minutes instead of every 15? What can be done to help keep it down? I'm really not having an issue with the taste and I just suck on a pineapple lifesavor afterwards.....I'm just concerned about the fact that I've only had one cup and I can already feel it creeping up the back of my throat a little =(

I think I may have made it =). I've had 7 cups and I don't think I'm going to take the last one because my last 5 movements have been pretty clear. Honestly, I don't think that last cup is going to make some huge difference....it wasn't nearly as traumatic as I thought it would be, though =)
