If you have followed the dietry guidelines in the days leading up to taking the prep and try and take it in the right timeframe, you should be ok. It is hard to drink as it tastes awful. I chased it down with black coffee. I have had morning appointments, so did the prep the night before. I couldn't actually get to sleep as I was still needing to go to the loo until 5am. So, you could start the prep earlier, as long as you don't eat and stop drinking water at the right time.

Hi thanks for your reply. I was actually wondering if I should start the prep earlier when I get it. But didn't know if that would be ok. I'm aiming for a morning appointment so I can get the prep over with. If am honest the prep is worrying me more than colonoscopy 

As long as your bowel is clear and you can manage the hunger, I would have thought it is ok. TBH, the prep is pretty bad lol, and yes, it's worse than the colonoscopy. Wear some loose fitting clothes with no belts and stay close to the bathroom.

I don't eat much anyway because of the problems I'm having  so think I can deal with the hunger lol. 

I also feel sick almost all the time, so worried I'm going to puke the prep up lol. 

It is usually flavoured, but tastes pretty bad. If you have ever had movicol before, that's all it is. Drinking black coffee helps cleanse the palette.

I'll try a black tea.

I've actually never tried anything that acts a laxitive. But I guess I'll understand what my little girl has to go through as she has to have movicol every few days and lactulose daily!! Really not looking forward to this bowel prep one bit :cry:
