1st Colonoscopy tomorrow (prep)

Hi,

So tomorrow I have my first Colonoscopy, I'm originally being sent for it because while having a TURBT getting a growth removed from my Bladder that turned out to be benign, the surgeons noticed a connection between my bowel and bladder.

When I went back for the results that were Benign, The Dr told me they looked at my images again from CT & my bowel was inflamed, they suspect I may have Crohn's. My symptoms don't really match up with it I think but still it needs to be checked.

So I'm on PlenVu for Prep, I took dose 1 at 6pm this evening (Ireland)

It's now after 10pm & I have only gone to the toilet twice, both times I didn't feel like I needed to rush to the toilet, but it was watery like expected sorry of TMI. But now my stomach feels fine like I won't need to go again, this has me worried... Is this normal because I've read so many posts about people constantly being on the toilet or going to the toilet multiple times over the space of a few hours.

I have to do dose 2 at 6am, I feel like this first dose hasn't done a whole lot & I'm kinda worried my Colonoscopy will be cancelled?

Also,

I smoke Cannabis nightly for sleep, I know you're technically supposed to not use it but I really struggle to sleep without it due to anxiety & some pains, if I smoke tonight before 11pm would I be ok for my appointment at 1.15pm tomorrow? I plan on telling them about my Cannabis use just want to know if I will be ok smoking tonight as long as it's disclosed to the Dr and anesthesiologist?

Thank you
