ok i'm having a colonoscopy tomorrow and i've been on a liquid diet all day. I drank the first bottle of phospho soda 21/2 hrs. ago and nothing yet . How long does it take to make you start going?

It took about an hour and a half - two hours for it to kick in for me. Drink A LOT of water - when you think you've had enough, drink more. It'll help things move along faster and it'll stop you from getting severely dehydrated.

Good luck!

I agree...lots of water!!  It will help tremendously.  Although when I did my colonoscopy the first time, I was already having so much diarrhea, it didn't matter!!

Diagnosed with crohn's in January 2008! 
Pentasa 1000 mg 4 times a day
On Topamax twice daily for migraines
On nexium - continuing for a month or so...the pred upset my tummy pretty bad. :-(
I am 27 years old and have been married for 2 years.  I cannot wait to try to have children so I want to get this under control!!

Yes, drink as much water as you can.  If you are not in pain I would suggest moving around a bit, even if it is walking through your house.  I didn't have anything for about 2 hours then it all kicked in.

The water stimulates the gut to start emptying, the phosphosoda needs the water to help it do it best job.
